my fiance and i are buying a house, in the country and will be moving shortly, from our crowded town house. we were talking the other day about good big dogs, (we planned on purchasing 2 toy dogs), as i would be home alone alot with our 2 small children. i have never owned a big dog and was curious if anyone had any suggestions on a good big dog, that would be faithful to our faimly and be good at protecting our home and our children. i am worried a dog will turn on one of our kids, and that could turn into an ugly situation. i kinda didnt want to start with a puppy, as i am already trying to potty train a 2 year old. any suggestions??
