Large dog issues or problems?

Wow, this thread sure has taken on a life of its own! My original question was if anyone had problems while traveling with large or restricted breed dogs. The answers have been very helpful. I was worried about traveling with our Staffordshire Bull Cross, especially since we are recently retired and planned to travel to Arizona for the winter. We never intended to own a pit bull, let alone travel with one, but life takes strange turns. Our dog was rescued as a pup by our son, we were aghast at the thought of having it live in our home, yet she has turned out to be probably the best dog we have ever owned. Five and a half years on, we've retired, sold our house and are now full timeing with our dog. We are always aware that not everyone likes dogs, especially ours. So far we have not had any problems anywhere, even parks with breed restrictions. On occasion when small dogs get aggressive towards our dog, she goes into pit bull mode and responds accordingly, but thankfully nothing has ever come of that. So far so good. By the way, we are loving being in Yuma! Life is Good.
