Meet Penguin Male DOB: May 19, 2023 Weight: 22 lbs Breed: Jack Russell Terrier / Rat Terrier Mix Neutered (Fixed) Vaccinated Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Penguin is an outgoing, friendly little guy with a fun personality and a big zest for life packed into a small body. He loves being around people, enjoys interaction, and carries himself with the confident, entertaining energy Terrier lovers know and adore. He has matured beautifully into a lively companion who still enjoys playtime and activity while also loving affection and companionship from his humans. Penguin thrives when he feels included and part of the action. As a Jack Russell Terrier / Rat Terrier mix, Penguin may show traits such as intelligence, curiosity, alertness, and playful energy. Both breeds are known for being highly engaging, clever little dogs who enjoy staying mentally and physically active. Penguin would thrive in a home that can provide: Daily walks and playtime Mental stimulation and engagement Structure and consistency Companionship and inclusion as part of the family He would make a wonderful companion for someone looking for a social, entertaining, and affectionate dog with lots of personality. Training, Adjustment & What to Expect Many rescue dogs come from very different backgrounds. Some may have previously lived in homes, while others may have come from the streets, overcrowded shelters, neglect situations, or environments where they had little structure or guidance. Because of this, most rescue dogs arrive with only basic training at best, and some may have had no formal training at all. Even dogs who appear well-behaved in foster care or at the rescue are still adjusting and learning. The rescue environment itself also does not always allow for extensive one-on-one training. While we work hard to provide safety, structure, socialization, and basic guidance, adopters should be prepared to continue training and support after adoption. Penguin will benefit from: Positive reinforcement training Structure and consistency Continued socialization and engagement Mental stimulation and routine Patience during adjustment periods Please remember the 3-3-3 Rule: 3 days to decompress 3 weeks to learn your routine 3 months to fully feel at home With patience, stability, and commitment, rescue dogs often blossom into deeply loyal lifelong companions. Owner Responsibilities & Veterinary Care Owning a dog is a lifelong commitment that includes daily exercise, companionship, routine veterinary care, training, mental stimulation, and financial responsibility. Penguin will need: Daily walks, exercise, and interaction Continued training and engagement Routine wellness exams and preventative veterinary care A safe, stable, indoor living environment Consistent veterinary care, proper nutrition, preventative care, and emotional stability are all essential to helping him live a healthy and happy life. Penguin is an indoor family dog and is not to be chained or left outside.

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.

Story
Hi! I'm Sparky!! I am guessed to be a 6 yr old Jack Russel mix, and a 15 lb, lap-loving, blanket-burrowing, attention-hogging goof ball! I love love love being with my people! I will admit, when I first meet people, and I don't know them yet, I am unsure if I can let my guard down and I will put up a tough front But it only takes a little patience, and letting me check you out at my pace (and maybe a treat or two), and I will be glued to your side!! I wanna sit with you on the sofa, hang out with you in the yard, and cozy up under the covers at night (I'm a most excellent cuddler!!) I am good with the other dogs and cats at my foster home, too. I am looking for a home where I can get loves and scritches and be your bestest friend!! I'm staying in Cheyenne right now, so let my foster Mom know if you want to meet!

Story
Dollie is a 5 yr old JRT and just a doll! Such a sweet girl! Dollie is special needs, she is completely blind. But this doesnt stop her from exploring. She does great on walks, navigates stair and the yard fine, plays with squeaky balls. You will often forget she is blind. She likes other dogs, doesn't motice the cats. She is potty trained, and I believe she could be free roam in a blind safe environment. Dollie loves all people. Loves to snuggle. Apply to meet Dollie at her foster in Evans.
