I think that they are brilliant!!! They seem to be very smart. I just found out an interesting fact about the breed from Animal Planet's Dogs 101, and I thought I knew it all already!!! They have a bigger brain per body size than any other breed of dog. That explains why I think they are so smart! They have to put all that brain to use somehow!!!!!! Awesome. What is the difference between Apple head and Deer head? Apple head is the breed standard set by AKC. They have a larger, rounder dome (top of the head) with a 90 degree angle coming down from the top of the head to the snout and have shorter snouts. Deer heads are more slender on the top of the head and have a little more of a slope from the top of the head to the snout and a little longer snout.
