Male water spaniel , to neuter or not to
I should add, that my trusted vet and I discussed in detail my options with my dog, and we decided that neutering at 9 months old was the appropriate option for me and my dog. But I'm sure the internet knows better...
The bottom line is watspan has it 100% correct on this topic. Discuss this with your vet. End of story.
If you don't have issues, I'd have him neutered at north of 12 months old.
