Meet Travis Friendly, Playful, and Ready to Grow Into Your Best Friend Gender: Male | DOB: January 18, 2026 | Weight: 40 lbs | Expected Size: Medium-Large Good With: Dogs âï¸ | Kids âï¸ | Cats: Unknown Personality: Playful | â¤ï¸ Friendly | Social | Happy Medical: âï¸ Neutered | âï¸ Vaccinations Up to Date Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. â¤ï¸ Personality & Breed Information Travis is a handsome 8-month-old Border Collie/Terrier mix who currently weighs about 40 pounds. He's a friendly, playful young dog with plenty of growing, learning, and loving still ahead of him. Travis is at such a fun age. He's no longer a tiny puppy, but he's still very much a youngster discovering the world. He'll need a family ready to enjoy his playful personality while also helping him develop into a well-mannered adult dog. Travis is affectionate, people-oriented, playful, loyal, athletic, and enthusiastic about spending time with their families. At 40 pounds at only eight months old, Travis should be considered a medium breed dog, although his exact adult weight cannot be guaranteed. His ideal family should be ready to provide him with: Daily walks and age-appropriate exercise Playtime and enrichment Positive-reinforcement training Continued socialization Consistent household rules and boundaries Mental stimulation Plenty of affection and family time Travis isn't looking for somewhere to simply finish growing—he's looking for the family he'll grow up with. Training, Adjustment & What to Expect At seven months old, Travis is entering adolescence, an important stage for continued training and social development. Rescue dogs may arrive with basic training at best, so adopters should be prepared to continue working on house training as needed, leash manners, basic commands, recall, calm greetings, appropriate play, and household boundaries. Because Travis is becoming a bigger, stronger dog, teaching good manners now will help set him up for success as an adult. Training should remain positive, consistent, patient, and rewarding. Young dogs need repetition, and mistakes are part of learning. The 3-3-3 Rule 3 Days to decompress and begin feeling safe 3 Weeks to understand his new household routine 3 Months to fully settle in, build trust, and feel at home Travis may be friendly and outgoing, but he still deserves time to adjust to his new surroundings and learn what is expected of him. Owner Responsibilities & Veterinary Care Travis is neutered and up to date on his vaccinations. His future family should continue routine veterinary wellness exams, recommended vaccine boosters, flea/tick/heartworm and parasite prevention, dental care, quality nutrition, healthy weight management, grooming and nail care, and veterinary treatment whenever needed. As a growing medium-large breed puppy, Travis should receive age-appropriate exercise and nutrition while his body continues developing. His veterinarian can help guide his family on healthy growth, body condition, diet, and exercise as he matures. Adoption Information If you are interested in adopting Travis, please complete an adoption application at: https://www.ozzieandfriendsrescue.org/adoptions Ozzie and Friends Rescue is a Los Angeles-based nonprofit dedicated to rescuing dogs in need and helping them find safe, loving forever homes. While based in Southern California, we coordinate safe transportation for approved adopters throughout the United States. Adopting a young dog like Travis means committing not only to the adorable puppy in front of you today, but also to the adult and senior dog he'll eventually become. Travis is friendly, playful, growing fast, and ready for his next chapter. Give him the training, adventures, security, and love every young dog deserves, and you'll get something pretty wonderful in return—the chance to watch your puppy grow into your lifelong best friend.October 26, 2026, 9:57 am

Story

Meet Cassidy – A Loyal and Happy Lab/Collie/Shepherd Mix! DOB: 10/3/2022 | Weight: 76 pounds | Female Cassidy is a stunning Lab/Collie/Shepherd mix with a big heart and an even bigger personality. At 3 years old, she’s in the prime of her life—healthy, energetic, and full of love to give. Cassidy is known for her loyal spirit and happy demeanor. She absolutely adores her people, and with her affectionate nature, she’ll make a wonderful companion for an active and dedicated family. Breed Info: A mix of Labrador Retriever, Collie, and Shepherd, Cassidy combines intelligence, energy, and devotion. These breeds are known for their trainability and loyalty, but also for needing structure, exercise, and mental stimulation. Cassidy is a great candidate for agility work, hiking adventures, or simply being your best buddy in life. Special Notes: Cassidy is a spirited girl who loves to explore! She does have a talent for jumping fences, so she will require a home with a very secure, tall fence (or someone committed to leash walks and supervised play). She is currently enrolled in a basic training course and making wonderful progress. Continued training will be key to helping her thrive and channel her energy in positive ways. ‍‍ Owner Responsibilities: Cassidy’s new family will need to: Provide daily exercise and playtime. Continue with her training to reinforce good manners. Ensure a secure environment to keep her safe. Offer patience, structure, and plenty of love. &#226&#154&#150&#239&#184&#143 Things to Consider: Cassidy is best suited for an active household that can keep up with her energy. Landlords and property owners should be checked if you rent, as breed restrictions sometimes apply. Families should be prepared for her enthusiasm—she may not be best for homes with toddlers, but will love older children. The 3-3-3 Rule: Remember the adjustment period: 3 days to decompress. 3 weeks to learn your routine. 3 months to fully feel at home. Vet Care: Once adopted, getting Cassidy to your vet is important for a checkup and to establish ongoing care. &#226&#157&#164&#239&#184&#143 Why Cassidy Will Be a Great Addition: Cassidy isn’t just looking for a home—she’s looking for her forever partner. She has all the qualities of a best friend: loyal, protective, playful, and loving. With her happy spirit and willingness to learn, she’ll bring joy and companionship to the right home. She will thrive with someone who sees her spirited energy not as a challenge but as part of her charm. Cassidy is ready to love and be loved—could she be the one for you?

Meet Gum Drop A Happy Little Adventure Buddy Ready to Find His People Breed: Australian Kelpie / Border Collie Mix Gender: Male | Age: 09/14/2025 | Weight: 24 lbs (small medium) Good With: Dogs âï¸ | Kids âï¸ | Cats âï¸ Personality: Happy | Outgoing | Playful | Adventurous Medical: Not Provided Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. â¤ï¸ Personality & Breed Information Gum Drop is an adorable Australian Kelpie/Border Collie mix weighing approximately 24 pounds. He's an outgoing, happy young dog who's ready for adventure and excited to find people to share it with. Gum Drop is friendly with dogs, cats, and children. His social personality and manageable size could make him a great companion for a family looking for a fun young dog who enjoys being included. Australian Kelpies and Collies are often intelligent, athletic, playful, energetic, affectionate, and eager to engage with their people. Gum Drop may share many of these characteristics. He's likely to appreciate a lifestyle that gives him opportunities to walk, explore, play, learn new things, and use his brain. Interactive toys, sniffing games, positive training sessions, and outdoor adventures can all help keep an active young dog fulfilled. Most of all, Gum Drop needs what every young dog deserves: a committed family who will make him part of their life. Training, Adjustment & What to Expect Gum Drop is still young, so continued training will be an important part of helping him mature. His adopter should be prepared to continue working on leash manners, recall, basic commands, household boundaries, calm greetings, and any house or crate training that may still be needed. Training should be positive, consistent, patient, and rewarding. The 3-3-3 Rule: 3 Days to decompress and begin feeling safe 3 Weeks to learn his new household routine 3 Months to fully settle in, build trust, and feel at home Owner Responsibilities & Veterinary Care Gum Drop's neuter, vaccination, and microchip status were not provided. His future family should review his medical records with their veterinarian and continue routine wellness examinations, vaccinations and boosters as recommended, neutering if not already completed, parasite prevention, dental care, quality nutrition, grooming, exercise, and veterinary treatment whenever necessary.

** If you are interested in Dixie, please fill out our adoption application at http://farfels.com/farfels-rescue/adoption-form/ ** There's nothing quite like puppy energy and silliness! Dixie is a gorgeous 5 month old Blue Heeler / Border Collie mix who is as sweet, smart, and playful as she is adorable! She is 24 lbs, and estimated to be around 50-55 lbs full grown. This beautiful girl is coming to us with her sisters after we rescued them from a high-kill shelter in Texas where we knew these precious puppies simply couldn't stay. Now Dixie is ready to find a family of her very own! Dixie is a happy, social, puppy! She loves to play and loves making friends. You may see from her photos, but we took her and her sisters to a rescue puppy yoga event, and Dixie was the life of the party! She was bouncing around, making friends with EVERYONE! Any time someone would sit down on the yoga mat, Dixie was right there to give them face kisses! She is a very social, sweetheart! Dixie loves other dogs, and absolutely LOVES to play! She enjoys running around, wrestling with her puppy friends, and generally having the best time wherever she goes. She has that fun, energetic puppy personality that will keep her family laughing and entertained. From Dixie's foster: "Dixie is doing amazing! She is super smart, funny, friendly, playful, and social! She is still a puppy so needs some basic training, but she is SO smart and food motivated so training her will be a literal breeze. Dixie knows know stranger! She would absolutely love an active family that wants a friendly dog to hike with and bring to social events. She is teething right now, so LOVES toys, especially anything that has a squeaker in it. " Dixie is going to make an amazing companion for someone who is ready for the commitment and adventure of raising a puppy. She's smart, affectionate, social, and absolutely precious, and we can't wait to watch her grow into the incredible dog we know she can be. Dixie would do great in a home with someone who works from home, and has the time and energy to train a young puppy. We would feel comfortable with her going to a family with kids 6+ years of age. Since Dixie is just a puppy, she's a blank slate just waiting for a kind and patient human to show her the way. We are not willing to adopt to someone who is unable to commit to taking Dixie to puppy socialization classes and training. Dixie has been fully vetted, and is in great health. She is fully vaccinated. Dixie is too young to be spayed, but when she is 6-8 months old we will cover the full cost. Spay is REQUIRED to finalize any adoption. Per the state of Colorado, you will be legally considered a foster until the dog is spayed. Spay must be done before or by the time she turns 1 year old, NO later. Farfel's Rescue is a fully foster based rescue, and offers a one week trial with every adoption. We feel that this is much more beneficial to not only the dog, but the adopter too. We believe that only getting 20-30 minutes with a dog before deciding on a lifetime commitment is not a fair amount of time to the adopter, or the dog. Therefore we give adopters one week with the dog to assure it is the right fit, and offer a full refund of their adoption fee should it not workout within the week trial. Farfel's Rescue has been doing adoptions this way since 2005 and is thrilled to adopt out 400 dogs each year. Dixie is available for adoption now! If interested in this gorgeous, very cuddly/sweet and loving best friend, please fill out an application completely at http://farfels.com/farfels-rescue/adoption-form/ and submit. **PLEASE NOTE** If you're truly interested in adopting from us, please be sure to fill out our Farfel's Rescue adoption application found at the link above or at farfels.com. Adoption site applications such as Petfinder and Adoptapet don't provide enough information and therefore aren't useful. Our Farfel's application is the only initial tool we have to determine a great match for this very deserving pup. We're sorry, but in many cases, we're unable to get back to those that don't submit our Farfel's Rescue adoption application. Thanks very much for choosing rescue.

Story

There's nothing quite like puppy energy and silliness and then they put their heads quietly on your shoulder breathing their warm baby breath. These very loving and sweet as can be dogs are so pure and vulnerable that it's unbearable to think of them lost and alone or in an overcrowded high-kill shelter scheduled for euthanasia due to lack of space. Rosie, at just 5 months old and 24 lbs (anticipated to be approximately 50 lbs when full grown) was facing the end of her life before it ever began due to a lack of shelter space. Farfel's rescue partners are compassionate and loving and couldn't turn their back on this gorgeous girl with the great temperament. They rescued Rosie just in time to spare her life. Rosie is believed to be a Blue Heeler (Cattle Dog) / Border Collie mix. She is such a friendly, happy puppy, who is just waiting to make someone so happy! Rosie's foster dad had the following to say about her: "Rosie is a great puppy!! She has a great personality and is super social and not shy with anyone. Super fun, playful, and so sweet. She is an energetic puppy, and a great hiker!! She is now totally potty trained, too! We are over a week without a single accident in the house. She is so smart and learns really fast. She is in her teething stage so always wants something to chew on, so make sure to have lots of toys and chews ready for her. She is a great puppy!" Current research is very clear that the best diet we can provide for our pets is a fresh, human grade diet. Farfel's recommends Chi Diet (chidog.com) due to our personal experience with our own dogs. It's one of the most important choices we make for our dogs great health (far fewer vet visits) and longevity. Rosie is appropriately playful and inquisitive for her young age. She's also so loving and cuddly. Our sweet Rosie would be very excited to be a couch or bed dog and snuggle with her favorite people at the end of an active day. She's also SO smart and engaging - very typical of the super-smart herding dog breeds. We'd love for Rosie to find her forever home with an energetic retired couple or individual with the desire to train and enjoy a silly and super-smart pup. Rosie would also be thrilled with a younger family that works from a home-based office to love her up periodically over the course of the day. Sweet Rosie enjoys her relationships with all humans and dogs. We would prefer, however, to place her in a home with older kids (tail pulling or rough treatment with a puppy will create an adult dog that's fearful of children). Older kids can be active participants in a training regimen and friendship that's so important in a dog's development. Rosie enjoys her relationships with other dogs as well and would love playing hard and then enjoying the sunshine together on a beautiful day. Rosie will do well with any loving guardian who's invested in spending time with their pup. She's so pleasant and portable that she can be a part of any adventure. It can be a leisurely walk socializing with neighbors, a picnic in the park or a visit with family or friends. A car ride is also always fun, especially if it leads to a fun, dog-loving spot. At day's end, a spot on the couch or bed beside her favorite humans will speak to the loving nature of this sweet puppy. Rosie will be up to date on her vetting/vaccinations to be in line with our commitment to adopting out only healthy dogs. New research is clear that fixing a dog this young isn't in that dog's best interest. Farfel's is happy to cover all costs for Rosie's spay and microchip once she's one year old if one of our rescue vets is used. Spay is required to finalize any adoption. Applications are currently being accepted for this silly, sweet and loving best friend. An application can be found at http://farfels.com/farfels-rescue/adoption-form/. If interested, please fill out completely and submit. **PLEASE NOTE** If you're truly interested in adopting Rosie please be sure to fill out our Farfel's Rescue adoption application found at the link above or at farfels.com. Adoption site applications such as Petfinder and Adoptapet don't provide enough information and therefore aren't useful. Our Farfel's application is the only initial tool that we have to determine a great match for this very deserving puppy.

Story

Wanda is the perfect combo - the legs of a giraffe, ears of a fox, and fur highlights any hairdresser would be proud of. She is a sweet, sweet soul who is still learning to trust and settle in. She is a little uncertain of other people and dogs on walks but LOVES praise and looks to you for guidance. While she is really good at hanging while we work, or being lazy when we are, we know she's got some energy in there! We think she'd do great in an active home - whether that be going on runs, or hikes, or maybe even a medal winning agility dog if she aims high. We think she would thrive in a house with another dog sibling to show her the ropes. She becomes so playful once she has warmed up to another dog, and becomes much more confident with a buddy by her side. She immediately loved the visitors we've had to our house and we get full body wiggles and whines of excitement when we leave the room even just for a second and come back. She's a lover! Wanda is getting braver and more confident each day, and her puppy continues to come out! She could spend all day outside, watching the squirrels and birds, sniffing flowers and rolling in the grass. Potty training is a work in progress but we have already seen improvements. She has been sleeping in her crate at night and whining in the morning when she needs to get out. We have yet to see her use the bathroom on a leash however - she's stubbornly good at holding it and likes her privacy, so she consistently goes to a certain spot in our yard. She's very food motivated and responsive to any redirecting her away from things, especially for a puppy who is curious about everything! Don't you Wanda bring her home?! ##2841948##

Story

Meet Hassan Breed: Husky / Kelpie Mix Sex: Male DOB: July 17, 2022 Weight: 66 pounds Health: Healthy and vaccinated Hassan is a striking, intelligent boy with soulful eyes and a strong, resilient heart. He was abandoned and rescued from a very busy roadway, where he was dangerously close to being hit by cars. Thankfully, he was saved in time — and now he’s ready for the safe, loving forever home he deserves. Despite his difficult beginning, Hassan has remained loyal, playful, and full of life. Personality Hassan lives peacefully with other dogs and enjoys being around humans. He loves going out for walks, running, and exploring the world around him. Playtime is one of his favorite things — especially chasing a ball or carrying around plush toys. When he first meets new people, Hassan can be a little reserved or cautious. But once he gets to know you, his personality softens beautifully, and he becomes affectionate and loyal. He just needs a little time to feel secure. Hassan does not like sharing his food, so he would do best in a home where feeding routines are managed thoughtfully and respectfully. Breed Info: Husky / Kelpie Mix This is a smart, athletic mix that typically brings: High intelligence and problem-solving ability Strong loyalty to their people Active energy that thrives with exercise A desire for engagement and purpose Hassan will do best in a home that enjoys walks, outdoor time, and mental stimulation. Owner Responsibilities Hassan will thrive with: Daily exercise (walks, running, play sessions) Continued positive reinforcement training Clear structure and consistency Managed feeding routines due to food guarding Patience while he builds trust with new people He is not difficult — he simply needs leadership, routine, and love. &#226&#154&#160&#239&#184&#143 Things to Consider Before Adopting Before bringing Hassan home, please consider: Do you have time for daily exercise and enrichment? Is your home and lifestyle stable long-term? Are pets allowed where you live? Can you provide structure and manage feeding separately if needed? Adoption is a lifelong commitment, especially for an active breed mix Hassan deserves a home that won’t give up on him. Vet Care Although Hassan is healthy and vaccinated, adopters should schedule a visit with their own veterinarian as soon as possible after adoption to establish care and continue his wellness routine. The 3-3-3 Rule First 3 days: Hassan may be cautious and observant as he adjusts. First 3 weeks: He’ll begin to learn your routine and feel secure. First 3 months: Trust deepens, and his loving, loyal personality truly shines. Patience and consistency will help him flourish. Why Hassan Is Special Hassan survived being abandoned and left in danger — yet he still chooses trust. He is playful, intelligent, and deeply loyal once he bonds. He deserves stability, safety, and someone who will show him that he is finally home for good. If you’re ready for an active, devoted companion who will stand by you with loyalty and heart, Hassan is waiting for you If you are interested in adopting this amazing dog, please follow the link https://www.ozzieandfriendsrescue.org/adoptions and fill out an application Thank you for choosing Ozzie and Friends Rescue.

Story

Meet Mr. Oreo Male Age: 7/23/2022 Weight: 42 pounds Breed: Australian Cattle / Catahoula Leopard mix Neutered (Fixed): Yes Vaccines: Up to Date Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Mr. Oreo's life hasn't always been easy. At some point, the family he trusted was no longer able to care for him, and he found himself without the security of a home or the comfort of someone who loved him. Like so many wonderful dogs, he didn't understand why his world had suddenly changed. Yet through it all, Mr. Oreo never stopped believing that kindness still existed. When he arrived at our rescue, it didn't take long for everyone to fall in love with him. His tail wagged the moment someone spoke to him, and despite everything he had lost, he greeted each new day with hope instead of fear. Dogs like Mr. Oreo remind us that love can survive even the hardest chapters of life. Mr. Oreo is a loving, happy boy who simply enjoys being with people. He has a warm, affectionate personality and is happiest when he can be close to his family. Whether it's joining you for a morning walk, relaxing at your feet while you watch television, or greeting you at the door after work with a wagging tail, Mr. Oreo is the kind of dog who makes a house feel like a home. He has reached a wonderful stage in life where he is playful without being overly energetic. He enjoys getting outside for walks and adventures but is equally content spending quiet evenings cuddling with the people he loves. His calm, joyful personality makes him a wonderful companion for families, couples, or individuals looking for a loyal best friend. Mr. Oreo would thrive in a home prepared for: Daily walks and moderate exercise Plenty of love and companionship Positive reinforcement training Mental enrichment through toys and interactive activities Structure, consistency, and routine A lifelong commitment to his emotional and physical well-being Mr. Oreo has already experienced what it feels like to lose a home. Now he's hoping to find a family that will promise him something he's waited his whole life for—a forever home where he'll always be loved, always be safe, and never have to wonder if he's wanted again. Training, Adjustment & What to Expect Like many rescue dogs, Mr. Oreo may need a little time to adjust to a new home, routine, and environment.
