Alyssa, I agree. There are plenty of big breed dogs that are not well mannered either. In fact I have one of them. Zoee is horrible on leash around other dogs. She flips out, the hair on her back raises and she barks her head off. She looks like she wants to tear the other dog apart. But once she meets them (if the owner is not running the other way) she is all butt waggles and wants to play.
I'm hoping to learn some more techniques in Taggarts training class, since another dog has that issue too. Also, I'm hoping to meet up with Sophie (Giselle) and have her help me too.
