Two years ago, I lost the last of my dogs. Both my German Shepard, Heidi and my Pitbull, China, lived to be 14 and 16 years old respectively. I guess I have grieved so much that I'm not ready to have a dog of my own yet. However, I really do miss having a dog. I love them so much. I think the reason my dogs lived healthy lives is that I was religious about walking them and paying attention to them. I walked them everyday, at least twice per day. Long walks, too. I'm not opposed to walking a mile or so, (an hour walk). I'm also not opposed to picking up poop. I always carry bags with me and I think of it as a responsible dog owner to pick up after your dog. I know how to handle dogs and what to look for should they be stressed when meeting other dogs. Both my dogs were very territorial when it came to meeting other dogs in the park. I took both of my dogs to Dog Obedience classes and I know how to get them out of a situation should they become aggressive when meeting other dogs. Usually, with Heidi and China, I would shorten their leash and pull them far away from other dogs. I was always vigilant and really wouldn't allow strangers to pet them, because I didn't want to take chances that they would bite anyone. I am well-versed with the Minneapolis Animal Control rules, as they are somewhat biased against pitbulls. Depending on whether your dog is leash trained, would be the size dog I could handle. I know that I can handle a dog who is at least 40 lbs. However, if you have a giant dog who is leash trained, I would be willing to walk that dog as well.
