Story
🌸 Meet Ophelia — The Softest Goofball You’ll Ever Love! 🌸 If gentle souls came in dog form, they’d look exactly like Ophelia. This sweet, slightly clumsy beauty is all heart, all softness, and all about the snacks. Ophelia is a certified Pet Acceptance Professional — head, belly, booty, you name it, she’ll happily accept all pets with a look of pure bliss. And while toys aren’t really her thing yet, she did proudly grab a bone today and parade it outside like she unlocked a new life achievement. She’s quiet as a cloud, content to snooze while the humans handle all the boring stuff. But don’t be fooled — when she gets excited (usually for food because… same), she does the cutest tiny spins that will melt you instantly. Ophelia’s crate manners? Immaculate. She settles in quietly, especially now that her crate is in the action zone where she can keep tabs on her people. She’ll head to the door when she needs to go out and knows grass is for potty breaks — a polite queen! 👑 She loves lounging in the backyard, isn’t phased by vacuums, blenders, or even surprise LOUD construction — apparently nothing can interrupt her chill. She knows some basic commands and is eager (and treat-motivated 👀) to learn more. She’s a wonderful mix of silly and sweet, with just a sprinkle of clumsy charm. The only thing she’s still figuring out? Leash world. Walks can make her a bit nervous right now, but she’s settling in and learning that the world outside isn’t so scary. With patience and gentle guidance, she’ll get there. If you’re looking for a soft, sweet, silly girl who wants nothing more than to be loved, fed treats, and nap while you live your human life… Ophelia is your girl. 💕 Ready to meet her? She’s ready for you.

Story
I found this puppy and his siblings behind my work in Stockton. I found his siblings homes but can't seem to find him one😞 He and his siblings were definitely abandoned but not malnourished. Im assuming someone's dog got pregnant accidentally and kept the puppies til the playful stage. He is sweet and quiet. Does need attention and has been hurt before (he and his siblings hid the first days with them and were scared by any fast movements). He's well behaved but definitely still learning (he's a puppy). He is still in potty training but doing well. Does well with other playful animals (cats and dogs). Loves car rides and pup cups! 🧡

Meet Rex, our 98-lb gentle giant with a heart just as big as his blocky head.

He thrives in a calm, structured home without too much chaos just a loving person or family who sees what a treasure he is. Neutered| 2 yrs old | 98 lbs | Mastiff Mix
