Well I had Max neutered last month short after he turned 6 months. He did not change a bit. They told us that he should not be jumping or running because of the incision but that didn't happen. From the first day we got him from the clinic he was jumping and running. I had the option of getting pain medicine for him which I did but then realized that I didn't need any he was not in any pain what so ever!
The next day after the surgery he was being himself and by the end of the week we were at the dog park and he was being himself.
I know its risky but the benefits are greater. My husband too was like no what about his manhood!!! But it's much better to have him neutered.
