Meet George Goofy, Silly, and Full of Puppy Fun—George Is Ready for His Forever Family Breed: Chihuahua / Terrier Mix Gender: Male | Age: 06/13/2026 | Weight/Size: 7 lbs currently (small) Good With: Dogs ✔️ | Kids ✔️ | Cats: Unknown Personality: Goofy | Playful | Friendly | Silly | Puppy Personality Medical: ✔️ Vaccinations Current | Neuter: Age-Appropriate/Pending Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. ❤️ Personality & Breed Information George is an adorable 3-month-old Chihuahua / Terrier mix weighing approximately 7 pounds. This little guy is a goofy, silly puppy who brings plenty of fun and personality wherever he goes. He's at the perfect age for exploring, playing, learning, and figuring out the world around him. George is good with other dogs and children, while his compatibility with cats is currently unknown. As a Chihuahua / Terrier mix, George may grow into a bright, affectionate, curious, playful, and spirited companion. Both Chihuahuas and Terriers can pack a surprising amount of personality into a smaller body, and George is already showing that he's no exception! Because he is still very young, his exact adult size, appearance, energy level, and temperament cannot be guaranteed. George would love a family ready to enjoy his puppy antics while also giving him the structure, training, socialization, exercise, and companionship he needs to grow into a confident adult dog. Training, Adjustment & What to Expect George may be cute and tiny, but he's still a puppy who needs to learn all the important skills that come with being a family dog. His adopter should expect normal puppy behaviors such as potty accidents, chewing, puppy nipping, bursts of energy, curiosity, and plenty of goofy mischief. Rescue puppies generally arrive with basic training at best. George's family should be prepared to work on house training, leash skills, basic commands, recall, appropriate chewing, household boundaries, and continued positive socialization. Training should always be patient, consistent, and based on positive reinforcement. 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 George may be ready to have fun immediately, but he should still be given time to adjust at his own pace. Owner Responsibilities & Veterinary Care George's vaccinations are currently up to date, and his neuter will be completed when age appropriate. Because he is only three months old, his adopter should continue his puppy veterinary schedule and complete any remaining vaccinations and boosters recommended by his veterinarian. His future family should provide routine veterinary care, parasite prevention, quality puppy nutrition, dental care, age-appropriate exercise, continued training and socialization, and veterinary treatment whenever needed. As a small puppy, George should also be handled carefully and protected from rough play, unsafe jumps, open doors or gates, and interactions that could accidentally injure such a little dog. Adoption Information If you are interested in adopting George, 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 puppy means committing to George through every stage of his life—not only while he's tiny and adorable. He'll need continued training, veterinary care, patience, exercise, companionship, and lots of love. George is seven little pounds of goofy puppy personality. He's silly, playful, friendly, and ready to make his future family laugh for years to come. Give this little guy the chance to grow up knowing that he's loved, safe, and finally home.

Meet Roxy One Eye, One Big Heart, and So Much Love to Give Breed: Chihuahua Gender: Female | Age: 09/09/2025 | Weight/Size: 12 lbs (Small) Good With: Dogs ✔️ | Kids ✔️ | Cats: Unknown Personality: ❤️ Loving | Affectionate | Friendly | Sweet-Natured Special Note: ️ Roxy is missing one eye Medical: Spayed and vaccinations up to date Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. ❤️ Personality, Breed Information & Roxy’s Story Roxy is a beautiful 1-year-old Chihuahua weighing approximately 12 pounds. This loving little girl has already been through enough to make her special—but she hasn't let her past take away her ability to love. Roxy was rescued and is missing one eye. While we don't have the details of how she lost it, what matters most is the dog she is today: a loving girl who is ready to move forward and find a family of her own. Dogs with one eye can typically adapt extremely well. Roxy may have reduced depth perception or a smaller field of vision on one side, but with a safe environment and a little consideration from her family, having one eye doesn't have to stop her from enjoying a happy, active life. Roxy is friendly with other dogs and good with children. Her compatibility with cats is currently unknown. As a Chihuahua, Roxy may share many of the traits associated with the breed. Chihuahuas are often affectionate, intelligent, alert, devoted, and deeply attached to their people. They may be little dogs, but they can have enormous personalities and form incredibly strong bonds with their families. Roxy would benefit from: Plenty of love and companionship Daily walks and appropriate exercise Positive-reinforcement training Mental stimulation and enrichment Consistent household routines Gentle handling A secure home and careful leash use Comfortable places to rest Continued veterinary care A lifelong commitment Roxy doesn't need someone to feel sorry for her. She needs someone to see the loving little dog standing in front of them and give her the life she deserves. Training, Adjustment & What to Expect At only one year old, Roxy is a young adult with plenty of life ahead of her. Moving into a new home will still be a big adjustment, and she should be given time to become comfortable with her new surroundings and routine. Rescue dogs may arrive with basic training at best. Her adopter should be prepared to continue working on: House training as needed Leash manners Basic commands Household boundaries Recall Comfortable handling Continued socialization Because Roxy has vision on only one side, approaching her calmly and allowing her to realize someone is there before touching her—particularly from her blind side—can help prevent startling her. Please remember the 3-3-3 Rule: 3 Days to decompress and begin feeling safe 3 Weeks to understand her new household routine 3 Months to fully settle in, build trust, and feel at home Patience, consistency, affection, and positive reinforcement will help Roxy understand that she's safe and that her new family isn't going anywhere. Owner Responsibilities & Veterinary Care Roxy's spay and vaccination status were not provided, so her complete medical records should be reviewed with her veterinarian. Because she has one eye, her remaining eye is especially important. Her family should make routine eye care part of her overall veterinary care and contact a veterinarian if they notice redness, squinting, discharge, cloudiness, injury, or changes in vision. Her future family should provide: Routine veterinary wellness examinations Vaccinations and boosters as recommended Spaying if not already completed Routine monitoring of her remaining eye Flea, tick, heartworm, and parasite prevention Routine dental care Quality nutrition and healthy weight management Daily appropriate exercise Mental stimulation and enrichment Continued positive-reinforcement training Veterinary treatment whenever illness or injury occurs A safe and comfortable indoor home For a small dog like Roxy, secure doors, gates, harnesses, and leashes are especially important. Her family should also supervise interactions and protect her from unsafe jumps or overly rough play. Adoption Information If you are interested in adopting Roxy, please complete an adoption application at: https://www.ozzieandfriendsrescue.org/adoptions Thank you for considering adoption through Ozzie and Friends Rescue, a Los Angeles-based nonprofit dedicated to helping deserving dogs find safe, loving, permanent homes. Although we are based in Los Angeles, California, we coordinate safe and reliable transportation for approved adopters throughout the United States. Roxy may see the world a little differently, but she loves with her whole heart. She's only one year old, and the best part of her life can still be ahead of her. She doesn't need a perfect home—just a loving, committed one that will choose her exactly as she is.September 30, 2026, 4:43 pm

Dodge is a small (8lb) sweet boy who is looking for someone special to help him build his confidence and show him that the world isn’t so scary. Once Dodge feels comfortable, his sweet personality really shines! He loves getting pets, giving kisses, and being around his people. He also has plenty of energy and absolutely loves playing with other dogs, big and small. He does wonderfully with his canine friends and would love a home where he can have plenty of opportunities to play and get his zoomies out!  Recently he has started running to the top of his fosters stairs with his toy, dropping it down the stairs so he has to go chase it, then running up the stairs with it again.  He is a smart, hilarious little boy.  He can be nervous at first so he’ll do best with a patient and understanding person who is willing to give him the time and reassurance he needs to come out of his shell.

Shy is a 2-3 year old Chihuahua Mix weighing about 8lbs.  Shy came to CO with 10 other small little dogs from a hoarding case in Texas.  When they first arrived they were terrified but have all started to warm up and really shine.  Shy is the sweetest little man.  He gets along great with other dogs (big and small) and even likes to play! He does take time to feel comfortable around new people and will need a human or family who can be patient with him while he warms up and learns to trust more.  It took him about 3-4 days in his current foster home for his true, goofy, loving personality to start comig out, so we assume his forever humans will need to have the same patience as his foster momma.  We would love for Shy to go to a home with another dog to keep learning from, and because he loves other dogs!  Once Shy's forever humans gain his trust he will be loyal, loving, incredibly snuggly, and just an amazing little guy.  It's so clear this little guy has so much love to give and now that he is feeling safe he just wants everybody to know!

Bruno is a 2-3 year old Chihuahua mix weighing about 13lbs.  Bruno came from Texas where he was part of a neglect case.  He was with multiple other dogs who's owner had grown old and sick. She was unfortunately having trouble taking proper care of all her little dogs, so animal control stepped in to get the dogs the care they needed.  Luckily, their owner was able to realize on her own that she was in over her head and she needed help rehoming all her dogs, for their best interest.  Bruno made his way to CO a few weeks ago and is now ready to find his very own forever family.  Here is what his foster Momma has to say about him: "Bruno is a shy pup that needs slow introduction but once he warms up he is sweet as can be. He loves hanging on the couch laying on soft blankets and loves to run around the yard with other dogs big and small). Hes is working hard on potty training and making good progress (he seems to be very smart!) He's good with older kids and we are guessing he would be good with anybody and anything since he is just the sweetest little love bug. He is also very chill and easy going.  He would do great in a home with anothe doggo but it's not a must as long as he is loved and his forever human has as much unconditional love to give as he does!"

Story
Ziggy is an incredibly handsome 5 year old, 29-pound Chihuahua / Cattle Dog mix. He is an affectionate and sweet boy who just wants to find his forever family. He was picked up as a stray and taken to an overcrowded, high-kill shelter in Houston, Texas. Farfel's rescued him and brought him to Colorado, where we know his perfect home awaits. From Ziggy's foster: "Ziggy is truly such a sweet, loving little guy. He can be a little shy when meeting new people, but once he feels safe, he completely blossoms into the most affectionate boy. He loves cuddling on the couch, sleeping in bed with me, and following me from room to room. If you're looking for a loyal shadow, Ziggy is your guy!" Ziggy is looking for a home with a big yard for him to run and play in. One of Ziggy's favorite things is spending time in the yard. With his playful and social nature, Ziggy adores spending time in the yard, chasing squirrels, and playing with other dogs. Walks are stressful for him, so a home with a yard where he doesn't have to go on neighborhood walks is ideal for Ziggy. He's a smart boy who knows tricks and loves to show them off. He's also a smart little guy who already knows commands like 'sit' and can even catch treats in mid-air! Ziggy genuinely enjoys other dogs, in the home, at doggy daycare, or anywhere off leash. He can't meet new dogs on leash, but anywhere off leash he loves doggy friends! He does great with other dogs in daycare. The daycare provider has the following to say: "Ziggy does very well in daycare. His best friends are Marvel, Bear and Maggie. He likes to follow around the person in the yard when he needs a break from daycare. He loves cuddles and is very playful. We love Ziggy!" Ziggy loves brain games to get treats, and enjoys eating his dinner from a puzzle toy. Because Ziggy has experienced so much instability throughout his life, he thrives on routine, consistency, and being close to his people. He would be happiest in a quieter home with someone who is home much of the day, works from home, or is retired. He may cry or howl when left alone, but he is always left loose in his fosters house and is never destructive. He just likes being with his people. Ziggy is 100% potty trained, and has wonderful house manners. Ziggy is in excellent health. He is neutered, fully vaccinated, microchipped, and heartworm tested. He is blind in one eye due to what appears to be an old corneal scar, but it doesn't bother him at all and he navigates the world beautifully with his good eye. Farfel's Rescue would like to see Ziggy continue with positive reinforcement training. A virtual or in-person force-free training class helps build confidence, strengthens the bond between dog and adopter, and sets every rescue dog up for lifelong success. Because of this, we're looking for adopters who are committed to continuing Ziggy's training journey. Training is so important in the future behavior of every dog. It's for this reason that we're unwilling to adopt to a family that doesn't make this loving choice. Farfel's provides a list of approved positive reinforcement trainers. Ziggy is available for adoption now! Applications are currently being accepted for this very sweet, loving and loyal 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 Ziggy 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 dog.

It's for this reason that we're unwilling to adopt to a family that doesn't make this loving choice. Farfel's provides a list of approved positive reinforcement trainers. Ziggy is available for adoption now! Applications are currently being accepted for this very sweet, loving and loyal 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 Ziggy 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 dog.

These pups are in Boulder, Colorado too!

Meet Taquito ❤️ Tiny, Sweet, and Ready to Be Someone’s Little Best Friend Breed: Chinese Crested Hairless  Mix Gender: Male | Age: 2 Years | Weight/Size: 7 lbs (Small) Good With: Dogs: Yes | Cats: Unknown | Kids: Yes Personality: ❤️ Sweet | Affectionate | Loving | Friendly Medical: ✔️ Neutered | ✔️ Vaccinations Up to Date Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. ❤️ Personality & Breed Information Taquito is an adorable two-year-old  weighing only about 7 pounds. He's a tiny little guy with a sweet personality who is ready to find a family to call his own. Taquito may be small, but little dogs can bring an incredible amount of companionship into a home. He's at a wonderful age—past the earliest puppy stage but still a young adult with many years ahead of him. Taquito is known for being intelligent, alert, affectionate, and deeply devoted to their people. Because Taquito is such a small dog, his family should always be mindful of his size. He should be handled gently and protected from situations where he could accidentally be injured by rough play, large dogs, or unsafe jumps. Taquito would thrive with a family that provides: Plenty of love and companionship Daily walks appropriate for his size Playtime and interactive toys Positive-reinforcement training Mental stimulation and enrichment Consistent household routines A warm, comfortable place to rest Safe handling appropriate for a very small dog A secure indoor home where he's part of the family A lifelong commitment Training, Adjustment & What to Expect Although Taquito is already two years old, every rescue dog needs time to adjust to a new environment. His adopter should be prepared to continue reinforcing house training, leash manners, basic commands, and household routines as needed. Small dogs benefit from the same consistent training and boundaries as larger dogs. Please remember 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 Patience and positive reinforcement will help Taquito understand his new environment and develop a strong bond with his family. At only seven pounds, safety is especially important. Taquito should be securely leashed or contained when outside, and his family should make sure doors, gates, fences, and other potential escape areas are secure. Owner Responsibilities & Veterinary Care Taquito is already neutered and up to date on his vaccinations, giving him a great start toward a healthy future. His adopter should continue providing: Routine veterinary wellness examinations Recommended vaccination boosters Flea, tick, heartworm, and parasite prevention Routine dental examinations and dental care Quality nutrition appropriate for his size Healthy weight management Regular age-appropriate exercise Mental stimulation and enrichment Continued positive-reinforcement training Veterinary treatment whenever illness or injury occurs A safe and comfortable indoor home Dental care can be particularly important for small breeds such as Chihuahuas, so regular dental monitoring and good at-home care should be part of Taquito's lifelong routine. Adoption Information If you are interested in adopting Taquito, please complete an adoption application at: https://www.ozzieandfriendsrescue.org/adoptions Thank you for considering adoption through Ozzie and Friends Rescue, a Los Angeles-based nonprofit dedicated to helping deserving dogs find safe, loving, permanent homes. Although we are based in Los Angeles, California, we coordinate safe transportation for approved adopters throughout the United States. Taquito is just seven pounds of sweetness waiting for a family of his own. This little guy doesn't need much space—but he does need a whole lot of love, a safe place to call home, and someone committed to being his person for life. ❤️September 30, 2026, 4:43 pm
