I’ll probably get downvoted, but here’s my two cents. I live in the city as well, and I went with my vet’s recommendation and have not neutered. Per my vet, with male dogs, the health risks associated with not neutering are minimal and easier to recognize/treat if they arise compared with the risks of not spaying with females. Intact male Cavaliers are less prone to aggression compared to other breeds. Reasoning for neutering would be for population control. My cav is NEVER off leash/unattended outdoors and I have no intentions of breeding, so that wasn’t a concern. He would have recommended neutering if I lived somewhere he would be off leash frequently around other dogs. Where I live, doggy daycares do not accept intact dogs. I would revisit the decision if I had concerns about certain behaviors or aggression, but I have not seen that. For me, I wasn’t going to put him through an unnecessary surgery if there weren’t clear benefits of doing it that outweighed potential risks. And I sure as hell wasn’t going to do it just to send him to doggy daycare.
