Oh my gosh, I didn't know that but it makes sense because one of my neighbors, a few years ago, had the ugliest, dumbest chocolate brown lab I had ever seen. He must have been one inbred son-of-a-gun.
I also didn't know the crossed eyes in Siamese cats were a result of messed up breeding. I always thought it was normal and really cute.
The dog on the left belonged to a friend... The dog on the right is my Logan, who was not small, he was actually an inch taller than the preferred height in the standard.
There's a couple different trends going on.... one, breeding for large, moose looking dogs that some think are better, stronger dogs for hunting. (I don't think they have any better endurance at all) and the other, breeding from a very small chocolate gene pool. There seem to be a lot of huge gangly chocolates ;~D
Oh - and that dog was also dumber than a box of rocks ;~D
Sweet, but slooooooooooooow.
