Story
Apply to Adopt Me! Sultan was left at a vet to be euthanized because his people didn’t want him any longer. He is 103 pounds of “good boy.”  Unfortunately he is still in boarding at the vet, until we find a foster or an adopter. This 1 1/2yo mastiff mix loves everyone, and has done so well in play time with other dogs. He loves to run outside, is super sweet and loves attention. Although he hasn’t been around children in boarding, he loves everyone, so bigger kids (due to his size) would probably ok. He does a little whimper when he needs to go outside to potty. He is crate trained, and is doing well with walking on a leash. This handsome boys can’t wait to find his forever home, could that be with you?  If so, please complete an app and tell us more about your family. January 24, 2026, 10:26 pm
