I haven't met a dog that I failed to befriend. Even the most shy, on-guard dogs I have met have warmed up to me to the point that they don't want me to stop petting them or playing with them. I've had dogs in my life since I was born. I have had a total of three different dogs of my own & have taken care of multiple other dogs as well. I am available 24/7 for home visits, dog walking, & am willing to stay overnight in your home with your dog when you leave on vacation. I'm also a rather big person, so if you feel you have a dog that's strength is difficult for a normal person to handle, it won't be a problem for me.
