At what age do you neuter your dog? My vet reccomends 6-8 months. I have done a lot of reading recently that the Humane Society and other vets are doing it younger and younger. They claim that the 6 mo rule is arbitrary and that the younger the pup, the easier the recovery period. Also, what is the average cost? My vet quoted $250.00 if he is over 50# at 6 mos. I was thinking of going through the Friends of Animals and getting a certificate for $64.00, but I would have to use a different vet.
