This may be a dumb question, but for those of you that have male dogs, how did he act after being fixed? That is at the top of our agenda for our chihuahua after the wedding and I just kind of want to be prepared. When we had our female great dane fixed she was lethargic for a day or two then back to normal. But she was also a puppy - Sebastian is almost 2. We're doing it for a lot of reasons, the main one being that the vet said it would lessen his chances of getting cancer. I guess I'm just wondering if they experience attitude changes and that sort of thing since we have two other dogs. The vet of course gives us an entire list of possible things but I'm interested in what others have experienced first hand.
