I am only guessing that since Watson was neutered the 28th of October, that is the reason for his change in attitude. The differences are obvious so I don't know of anything else I can pin it on. He is only a few weeks older since that unexpected surgery to get that large piece of Mexican blanket out of his blocked intestine. This coming week he will be only 7 months old. One nice thing is, with all the three males neutered, there is less all out fighting taking place over any knuckle bones, the nylon bone with bacon flavor or the Kong balls filled with treats. I still supervise with a watchful though when they have those on the floor or in the backyard. Anything food related has been phased out.
