I just thought of another incident. My fiancé’s Akita, Grizz was walking on his leash and a neighbor's dog wasn't. I think the other dog was a Boxer, so they are both pretty big dogs. Anyway, the Boxer is really friendly, but Grizz isn't. The Boxer came up to Grizz to greet him and Grizz grabbed his neck. The Boxer had to have stitches and he was pretty bad for a few weeks. I just think it is too dangerous for dogs to be off leash.
