I had big size dogs since I was 8 years old. In particular: 1 golden retrievers, 2 Labradors and 1 pitbull. I can teach them new commands and I have a flexible schedule so I'm basically always available with the right notice. I took care of the dogs in my neighborhood since I was 15 years old, they are usually all very friendly with me since the first walk. I'm available to keep them in my place if needed but there's also another dog so it depends on the breed and their temperament. If your dog likes to run, I'm a runner as well so I can be a good helper to keep them fit and in shape.In almost ten years that I walk dogs I never had an accident with other dogs or dog owners.
