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.

A darling chunk of asymmetrical charm! Honey has one short ear, and one blue and one hazel eye. She is thin, but enjoying three meals a day! An easy walking, dog friendly gal! Mellow and charismatic, she soaks up the love, and is looking for a loving home with caring people that are savvy with XL breeds and can give her the attention she craves, some training and consistency, keep up with social activities, and there will be lots of joy to be shared!

Story
Big Mac is a special boy, stealing hearts here at the SF SPCA. This 5-year-old Bull Mastiff mix is the epitome of a gentle giant. He may be a big fella, but goodness is he a gentle boy. He approaches slowly before nudging your hand and asking for pets and will lay calmly by your side or snuggle up in your lap. He may not know how big he is, but he definitely knows how to be a sweet and calm friend.Mac would be a great fit for any family! His peaceful nature makes him a wonderful companion for anyone. The shelter environment can be a bit scary for Mac so he may take his time to warm up to you here but once he gets home, he`s going to be the sweetest companion you could ever have. Come fall in love with our gentle giant today -- he`s hard to say no to!

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! 🧡

Hen is ready for a loving home!All puppies need extra help learning about the world around them, and to be comfortable with new people and new dog friends. We encourage all puppy adopters to enroll their puppies in puppy socials starting at 8 weeks, and puppy training classes by 10 weeks. Participating in these activities will help your puppy grow up to be a happy, confident, and a well-rounded adult dog. It is also essential to help them build positive association with the world, by pairing new experiences with delicious treats. Primary Color: Black Weight: 10.6 Age: 0yrs 0mths 9wks
