IF I had a male puppy now, and IF I could live through adolescent male-ness, my choice would be to wait until at least a year old. While cancer is NOT a big problem in our breed, there is VERY strong evidence that neutering before sexual maturity is a very strong risk factor for certain very bad cancers in other breeds. (hemangiosarcoma and osteosarcoma, both of which are a death sentence) Early spay/neuter also predisposes ALL breeds to ACL/CCL tears, something that we do have in our breed, though this can be surgically repaired.
That said, some adolescent male puppies are MISERABLE to live with, and because the two above named cancers are not not prevalent in our breed, even among spayed/neutered dogs, there is a much smaller risk factor. I neutered Kodi at 7 months because I didn't know what I know now. Would I have been able to make it to a year without neutering? I honestly don't know. He wasn't marking, but he was humping everything in sight.
I guess I could have lived through the humping, but I SURE don't want a marking dog!!!
Of course, the other thing you have to be VERY clear on is whether you are willing to be responsible for never EVER letting your un-neutered pet breed another dog!!! It's a big responsibility, and VERY important!!!
And especially in a breed like ours where the risks of early spay/neuter are not as dramatic as with some big breeds, (no WAY would I spay/neuter a Golden before 2 years old!!!) I can CERTAINLY understand where the convenience of neutering the dog earlier is worth the SLIGHTLY increased risk of problems, especially when it can increase the dog's quality of life. (like in the case of having to leave a puppy home alone for months on end because a day care won't take an unneutered dog after a certain age)
I think the "right" answer for when to spay/neuter is different for every dog in every family. I think you need to read a lot, understand the risk factors (in BOTH directions... there are some cancers, specifically mammary cancers, that are more common in dogs spayed later, but they are also a relatively curable form of cancer if caught early) and then make the decision that is right for your pet and your family. Some vets can be helpful in making your decision, others have an "early spay/neuter agenda", so that's the ONLY answer you'll get from them.
