Story
Do you like BIG dogs? She-Ra may be your girl! Despite her size, she is a lower-energy pup, who enjoys going for walks, but is mostly happy to hang out and just be by your side! She was brought to our shelter on 11/17/25 after being found in unincorporated Livermore. She hasn't been reclaimed by her previous person, so she's now looking for a new home! She-Ra is dog-selective, which is common amongst adult dogs, meaning that she may appreciate some dogs more than others. If you already have another dog at home, we'll ask you to bring them to meet her too, prior to adoption. Her adoption fee is $35, plus licensing (if applicable). Her spay surgery has been sponsored by our friends at the Tri-Valley Animal Rescue! She-Ra qualifies for Senior Sunday! Adopt her on a Sunday and we'll waive her adoption fee! ## See video of She-Ra at the end of the photo gallery! ## TVAR.org/find-your-pet-adopt/dogs-puppies/ She-Ra’s Shelter ID# is 88279. She is an approximately 7-year-old, black, Mastiff mix. She currently weighs around 103 lbs. She has already been vaccinated, spayed and microchipped and is ready to go to her new home! She-Ra is located in kennel C-2. ** Age shown is an estimate only ** THIS IS A COURTESY POSTING If you are interested, please call the East County Animal Shelter at 925-803-7040 to see if this dog is still available.

Story
Meet Rex, our 98-lb gentle giant with a heart just as big as his blocky head. This stunning red Mastiff mix, just under 2 years old and already neutered, is the total package he is calm, polite, intelligent, and just the right amount of goofy. ✨ Why Rex is amazing: • Walks beautifully on leash • Knows “sit” and takes treats with a soft, gentle mouth • Affectionate once he warms up • Loves walks, lounging, and hanging with his people • May be cat workable with slow and proper intros 🐱❤️ In playgroups, Rex enjoys gentle play with both male and female dogs who don’t mind his big-dog enthusiasm. 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
