Golden retriever... because that is the type of dog my parents had when I was growing up and I have great memories of that dog!
Other people's dogs are always great. I love them all. But, I don't want one.
I love them all,but boxers are extra special to me.
chow i had a black chow who passed away
Border Collie. They are incredibly smart and athletic.
All of my favorite dogs have been mutts. The purebreds that I've been around have been more nervous or had some health issues. <br />
My most favorite was a small dog that I think was a poodle/terrier mix, though the jury is out on his parentage. Super intelligent and loyal little fellow.
I guess your criteria for what makes a good dog doesn't even remotely match mine.
