Yeah, someones got to have theirs removed. So, is it the dog, or you, OP?

absolutely not.
Dog lover here.
Plenty of dogs don't and live happy lives - my dog lived until a ripe old age.
Also think about how unhappy he will feel if it's done.
edit: the only way i would condone this is if he was very likely to be ill OR if he was very young and therefore wouldnt miss them as much. It's way too late now.
It will change his character. If you don't want his character to change then don't do it!

One question, would you like your **** removed?
We trained our dog to only do it to a duvet, whenever he gets "horny" give him the duvet and just train him to only use that. Everyone works out a winner, dog gets his fun and you get less leg fornication.
How did you train him to do this ....
I am in the same situation with my Labrador. He is a happy dog, and not aggressive. Every time we see the vets, they say to get him done. But i worry about putting him through unnecessary surgery. I something happened to him during the surgery i would be devastated.
My thinking on this is simple (like most of my thoughts) Vet says chop and you pay vet bill .... no chop no bill.
If you are not intending to breed from him or show him, get it done.

It's the responsible thing to do.
Cat owners should get theirs done too. There are soooo many unwanted puppies and kittens born because people didn't get them fixed, and this leads to a lot of animal cruelty (abandonment, etc).
Dexter is never out unless on a lead so next to zero chance of him becoming a dad, but I understand your point.
, although hes not been a leg humper so far. No, veterinary studies show that it significantly increases the risk of deadly cancers like osteosarcoma and hemangiosarcoma. Why put him through the stress of a surgical procedure if there's no issue with the dog?
