Working around lots of dogs for many years, we've also noticed that they tend to pick up the tone of the house. We've also noticed that most dogs really are a good judge of character! It's just my personal observation...but the best pets I've ever seen have been ones that were in some way rescued from a bad situation. It's almost as if they know they have been given a second chance. BTW, did you know that only about 40% (or less) ever make it out of the pound alive? My husband's first Weimaraner was rescued from the pound. Besides Breed Rescues, you can often find nice pure bred dogs (especially big dogs) at the pound. It seems that many idiots give their dog away when they realize it will get big.
