I have experience with different dog breeds and sizes, especially rescues. I also have personally trained 2 of my own rescue dogs. I also worked at a Dog Daycare where 15-50 dogs were at once. I make sure there are no animals or people in the yard before they go outside, that includes where people/animals are when they are on a walk. If I see a dog that’s loose, I try to distract my dog so he doesn’t see it and get to a safe distance that is not noticeable to the other dog.
