Story

Goof, derp, lover of life. Cjay is loving, loyal, funny – a tongue flopping, trotting next to you kind of bestie. He’s a great hybrid dog who loves to enjoy the great outdoors and go on walks, play ball and bike ride. But he also is a chill couch potato who likes to cozy in and watch TV. Everyone who meets Cjay falls in love with him – he’s one of those dogs who doesn’t lack for personality haha and keeps you laughing. Cjay has been fostered by an awesome trainer so whoever adopts him will get a dog who has been through an in depth board and train program already. Cjay’s the right dog for an experienced family who are strong leaders with kind hearts to stay consistent with his training to continue to set him up for success. Approved adopters will receive training sessions so you know what Cjay knows to make the transition smooth :). Cjay’s favorite thing to do is play ball WHILE rolling in the grass at the same time 🤯 ❤️ He's available for adoption anywhere in SoCal.

I am a fun, loving boy who loves to play. My only fault is I do not realize my size. I think I am a lap dog. I am house trained, and good with most other dogs. I would prefer to meet potential companions before going to a new home. ##2427887##

Story

How this pet arrived:This pet was brought in by a community member on September 9, 2025. Why this pet is the one for you:Meet Jones! Jones is a total lovebug who's ready and waiting to find his new loving home. He adores people and will display his excited wiggles when he greets you. He can be a bit shy with new faces and places, but once he builds confidence, he'll share his playful and energetic side. He's very smart and treat motivated, and has already mastered "sit," "paw" and "down." Jones has been known to have big feelings around other dogs, and may do best as your one and only canine companion. Although he may not be a candidate for dog parks or other off-leash venues, there are lots of other activities you can do together to strengthen your bond!

Story

I Found Solo one year ago. He came to my condominium. a senior community where i live with my elderly mother. I fell in love with Solo and it breaks my heart to part from him. I am recently divorced and I have no one except my mom that has health issues. I am going to go live in an RV and I really want to bring my dog but find it very hard having my mother with me. I think he will do better in a place where he can run and have a family that gives him attention. He is supper funny. The smartest dog I've had. Loyal. Sweet The bad: he is stubborn. Tries to push your buttons because he wants to be the alfa. Can get territorial and protective. He stays in a boarding called Leashless in Menifee when I need to travel. The Trainers agree he is stubborn but supper cute. He is used to being inside and is always by myside. Please do not take him if you do not have the time for him. Because he is a Mastiff mix he is very strong and powerful and loves to run and chase squirrels.
