Story
Meet BRUCE!!!! He is in New York ready for a meet and greet. He’s our baby giant? As of November 1, 2026 I am about 9 months old and weigh 65 pounds! He has the cutest smile! You could see this cute smile very day if you choose him to be your forever friend. I’m still a baby, which means I’m a blank canvas just waiting to become your very best friend! I’m young enough to learn how to live happily with children, and with proper introductions and gentle handling, I could grow up to be an amazing family companion. Older children is probably better because I love to play and I don’t know my own strength. I would probably do better with an active family because I am use to exercising. Am I potty trained? I’m working on it! Crate trained? We’re practicing! Walking nicely on a leash? Let’s just say the leash and I are still negotiating our relationship. I’m a puppy, so I’ll need patience, consistency, training, and lots of positive reinforcement. In return, I promise to fill your home with laughter, puppy kisses, and enough cuteness to make you forget why you walked into a room in the first place. Ready to make Bruce part of your family? Apply today! If you feel that he is a good fit for you/your family, please complete an application from our site, miraclesforsatosrescue.org FOR IMMEDIATE CONSIDERATION, PLEASE COMPLETE AN APPLICATION! https://www.miraclesforsatosrescue.org/adopt Please then email the application back to us at miraclesforsatosrescue@gmail.com ------------------------------------- PLEASE READ: He is currently located in New York. We strive for our dogs to be adopted into the right home. The best fit for the dog is our priority. Please make sure you are ready to properly exercise and give a dog all it needs for fulfillment. In addition, we cannot guarantee the breed of any dog or expected adult size of a puppy. Please also note that any dog that is "house trained" will still need patience in a new home, new people, and a new schedule. Please be ready to house train ANY dog you adopt! Thank you for understanding.
