David- Boxer's are magnificent dogs. One of our friends had a boxer. We loved that dog. She was selective of whom she liked; she liked us. Brogen and I both thank you. Based on past experiences I believe that effects of male neutering is more apparent with humans than canines. Testosterone has staying power; I do not anticipate much change if any for awhile. Brogen is 3 y.o. and he is behaving like a 3 y.o. dog. Saint B's start slowing down activity-wise pretty early, but not at 3. He is definitely people friendly. Our concerns are his canine sociability. He was videoed getting along with other St. B.'s. He went from play to prey mode in the reception area with a little fluffy dog at the last vet visit. The other dog's owner's reaction to Brogen may have triggered what happened. I can redirect Brogen with a choke chain/leash pretty well. He really does not pull with me on the leash. Sadly I appear to be the only one so far. I really do not think that this dog was ever really or consistently walked. Wifey successfully walked him around the field for the first time the other day. We will seek some professional guidance for the canine socialization part of his training. The vets are comfortable with how we are managing the atrophied jaw muscles. We'll see.
