Yah, vets are a peeve of mine.
My vets office is actually staffed by 8 vets. I have my prefered vet, but occasionally we'll end up seeing another.
With Apollo, I got the usual lecture when they first saw him as a pup, about neuter. I finally shut them up by telling them we planned to show. BUT, for all the frustration of that first visit, they've never brought it up again, we had our discussion, they respect my decision, thats really what I require. And infact, after his hips came back OFA Excellent I've gotten questioned on if I "plan to let those genes that built those hips die with him??"
With Arty, my usual vet was out the week that we brought him in for his first checkup and I saw one of the other vets who I'd previously never seen. My concern with potentially having two intact males: same sex aggression. The vet's concern with my having two intact males: that they'd mark my couch......It wasn't a pretty discussion. Needless to say I try to avoid that vet now when possible. (for the record, we ended up neutering Arty when it turned out that one of his testicles never descended into the scrotal sac)
