Story
This handsome big guy is Moose, a sweet 2-year-old pup tipping the scales at 97 lbs of love! Moose has had lots of training under his belt and is fully crate trained, walks beautifully on leash, and is great with other dogs.Moose is neutered, up-to-date on vaccines, and ready to find his forever home. While he’s made great progress, Moose is still a bit timid and sensitive, so he’s looking for a calmer household where he can continue to blossom at his own pace. Because of his gentle, shy nature, he’d do best in a home with older kids who understand how to give him space when he needs it.Moose would love a family who can provide a quiet, structured environment where he can feel safe, loved, and part of the pack. If you’re looking for a loyal, kind-hearted companion with a big heart (and paws to match!), Moose may be the one for you! Located in Los Angeles, CAMarch 7, 2026, 3:29 pm

Story
Junior Mint came to stay with me when his family of four years began recently having legal issues. I have been fostering him for a few months, he has had to learn some new rules, as we have a senior cat. But, he learns and cooperates well. He is such a beautiful dog for the breed. I don’t think there is anyone he couldn’t get along with, such a happy dog, a little wary. I had him neutered on July 21st and all vet needs. He needs a home! ASAP It’s time for him to move on. 82lbs

Story
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##
