I finally found a place about an hour and a half from Rochester that holds dock diving classes. The first class starts on Sunday and it is being held at a boat launch off of a canal in Buffalo.
My guess is that this time of year the water is going to be VERY cold. This isn't much of a problem for Earl who loves swimming in the middle of winter, but I can only imagine that Kayden isn't going to do as well in it. I know for a fact he will jump in since there will be a ball or disc involved, but I'm wondering how safe it is for a dog with such a short thin coat to be jumping into cold water like that.
