Let me toss this out to you- Hottie was neutered very late- the reason is that his sister died in a teeth cleaning, and with the suspect of anethesia, we waited until he was 6 and half.. We also almost lost him! Not from the anethesia but from a tumor undetected by numerious vets his whole life! It was a little bigger than a walnut tucked up in the scrotum. He was seriously ill for 3 days. Now realize this- Hottie has had a few specialists over the years- top vets on the east coast- and no one caught it.. I made the neuter decession based on the fact I knew another male dog was coming into the house- and paced the floor with the knowledge Hotties sister died in such a routine of teeth cleaning. If he had not been neutered- the tumor would have strangulated- killing him in a painful death. Dont let fear NOT get him neutered- let KNOWLEDGE know once decided to breed is not in the benefit of the pups- do it now.. You may do him a big favor verses continueing to wait.. A favor you do not even know about as in the case of Hottie!
( BTW- HOTTIE WAS having exams yearly even twice a year knowing he was in tact and with the risk of surgery- and STILL it wasnt found..)
