I used to have a shelter dog which was a mix of american pit bull, boxer, gray hound, and what not. She was the most amazing personality and had a presence also for her 90 lb!. It took a few years to get her to behave on the leash but we had some good walks though she wanted to chase squirrels and sometimes even other dogs. So I am used to pullers and erratic behavior. I love going to dog parks and find new places to walk my dog. They spend their whole days at home and the walks is their link to the outside. I do have a full time job that I am trying to combine with dog sitting. We can discuss how many hours the pet can be left alone and find a solution. Often I can work from home as long as I am online. Now I travel some with my work so I don't want to get a dog, so I hope your pet can fill the furry gap in my life.
