Theo

My story

You can fill out an adoption application online on our official website.Meet Theo! Theo is a sweet 8-month-old male Mastiff who came to us as part of a heartbreaking breeder dump at a California shelter. Theo and his siblings were surrendered terrified and overwhelmed, likely having experienced very little outside of the property they came from. The shelter environment was especially scary for these pups, and the siblings were separated. Thankfully, AZ Mastiff Rescue was able to save five of them, and Theo is now learning what it means to live in a home, feel safe, and be loved. ❤️ Theo is currently in a foster home with a female Cane Corso named Roma, and he is doing wonderfully with her. He’s a good boy who shares his toys, enjoys his treats, and is learning to look forward to attention and affection every day. We are continuing to work on building Theo’s confidence as he adjusts to this brand-new world. He is mostly crate trained and making great progress with home life. For Theo, we would love to find a patient, understanding forever home that will continue helping him blossom. A home with another confident dog would be best, preferably a female, so he has a canine companion to help show him the ropes. Theo didn’t get the start in life he deserved, but his future can be completely different.
