I have owned several dogs and fosters for a combined total of 18 years experience. I have worked in pet store. I currently own 3 pitbull rescues and have been working constantly on correcting problematic behaviors and aggression towards other dogs I have worked one on one with trainers and can handle problem dogs. I haven't met a dog that I couldn't deal with or that didn't accept me. I have had more experience with larger breeds but still have dealt with dogs under 20lbs.
