I don't know about most people hating on Boomer dogs, but dogs generally earn a bad reputation for a few reasons. The owner himself and his practices, the amount of times a stud has been bred, and the dogs off him.

I personally don't like Boomer dogs, based on the opinions of others I trust for those reasons. They're all in the tri-state area and have seen a lot more Boomer dogs than I ever will, and they've probably seen more than everyone here on this thread. I have a few pups with some Boomer blood in them, so I'll have a little something to go on with these to see what they've added or taken away from what I already have here.
