An Akita was the first dog we noticed that about. It was only a 10 month old, but it ran right next to Shaye, touching her all the way and looking down at her, and kept turning her to the right - I don't really know whether it was trying to get Shaye back to the place we were sitting or whether it was an aggressive move, but the result was the same. There is a Shepard here in the neighborhood we live in. When the man who walks it passes by us, he has to practically get down and physically hold the dog, because it tries to charge Shaye, ears back, hackles up, barking its head off. I don't know if it's like that with other dogs. At the park, there was a young Shepard who initially started playing with Shaye, but when Shaye went up like she does and came down around the dog's neck area, it lowered to the ground, bared its teeth, growled and scared me to death, I thought I was about to see Shaye get picked up and shaken to death in those jaws. It was not in a playing mood any more. So, I figure better safe than sorry. The man who owns the Akita who was herding Shaye told me Akitas are bred to be guard dogs and are naturally aggressive in initial meetings - so why he had that dog at a public park is beyond me.
