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?

Story

Princess Tomboy here. As you know, we don’t get to pick our names and I am not a princess. Sure I’m petite and sweet with good manners but get me out there with the other dogs and I can hold my own with dogs twice my size. Speaking of that, I am in my Denver foster home with Tuuli, who is also available. She has become my best buddy. We would love to be together if that would be a possibility, but we also understand if it isn’t. You see I’m a confident little dog fully grown just over 20 pounds and Tuuli is closer to 45 pounds but for some reason she doesn’t understand how wonderful she is and she’s shy so she needs a confident buddy like me. Ok, more about me; I’m a happy playful girl with good recall, walk well on leash, I take treats gently and share with the other dogs, and while there are no children in the home, I have met some and seem to be fine with them. I definitely need a yard and another playful companion. I’m a little spitfire, I play hard and crash hard. I sleep through the night on the bed (OK so I’m a little spoiled already). I haven’t had any issues in the house so far when people are gone. If you want to bring some joy and happiness into your home apply for me now! Looking forward to meeting you soon and thanks for reading my story. Love, Tomboy. If you're interested in meeting me please fill out an application at www.thegooddogrescue.org (If you already have an approved application, please email thegooddogrescueadoptions@gmail.com with your interest in me!) My adoption fee is $300 and I am spayed, microchipped and up to date on vaccinations ##2732831##

Story

Alfie is the kind of dog who quietly becomes your right-hand guy before you even realize it. One look into those soft, sweet eyes and he’s either melted into your lap or settled at your feet like he’s always belonged there. He’s a happy, spunky little puppy with a surprisingly gentle, almost goofy presence—honestly, he kind of gives off a little platypus energy in the best way. Alfie came in as a stray after being hit by a car, but his leg is healing beautifully on its own and hasn’t slowed him down one bit. He moves through life with curiosity, resilience, and a constant little tail wag. He’s in that classic puppy stage—playful, a little mouthy, and learning boundaries—so toys and chews are key. He absolutely loves other dogs and would thrive with a playful companion, and he’s a big fan of snuggle time once he’s gotten his wiggles out. He's great on his leash, learning his house manners and overall is just a sweet little (getting bigger every day) guy. If you’re looking for a loyal little sidekick—equal parts playful, cuddly, and quietly devoted—Alfie is your guy. To meet him, go to eapl.com and fill out an application. His adoption fee is $375 May 25, 2026, 11:13 am

Story

Stella is an amazing dog! Well behaved, obedient, loves kids, gets along well with other dogs and cats. She is a bit of a velcro dog and always wants to be with you but can stay at home for extended hours alone. She doesn't like noisy, crowded places. Stella weighs about 40lbs. She gets daily walks and loves to go to the park for a game of fetch the ball. She is mostly under voice command and doesn't require a leash, although walks well on one when needed. She is very food motivated and will work for a treat! I am only rehoming her because I am moving out of the country for health reasons and it is too hard to ask her to make such a big move.

She’s active, friendly, and full of curiosity. Whether it’s chasing a ball, going for a walk, or exploring the backyard, Maya is always up for an adventure. She loves people and enjoys being part of the action—but when playtime is over, she’s happy to curl up near her favorite humans.

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.
