What's the best age to neuter my male dog for healthy growth?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! There is not rush to neuter male dogs. As long as he doesn't have behavioral problems and isn't marking it is fine to wait. Neutering does helps with an enlarged prostate, prostatitis and prostatic abscesses that can occur with older age. Just as an aside, most dogs do not reach social or bahavioral maturity until 2-3 years of age, so behaviors Nabi have now may change. I hope this helps!

If a dog is neutered while juvenile, ie not yet sexually mature or grown up, then the neutering will impact skeletal development. It means that it will take longer for the dog to become a mature dog, and some research shows there may be also a mental development deficiency. However there is no time at which a dog "must" be neutered. I would do that before he gets the idea of roaming, as this can become a habit and then neutering will not influence this behavior. so 1) there is no need to neuter a dog at all unless you want to keep it from learning how to roam or keep it from breeding. Not neutering will not influence his health negatively. 2) if you have your dog neutered you can have that done at any time in his life.

In large breed dogs (i..e Golden Retriever, Labs, Rottweilers, etc) the newer recommendations is to wait until the pet is 2-3 years of age before neutering to decrease the chances of inadvertently causing bone cancer. So I would recommend waiting a bit longer.

There are some studies that recently may have found a correlation between earlier neutering and an increased risk for joint issues. This is pretty new evidence and at this point I think it's not really clear what the risks and benefits are. I typically recommend waiting until a male dog has reached his adult size, usually around 1 year, to neuter BUT in situations where the dog is showing undesirable behaviors potentially related to sex hormones I strongly recommend neutering earlier. If you were planning on having him neutered by 8 months I doubt 1.5 months of growth would make much of a difference for his bones and joints, so I would considering scheduling the neuter now. You could always talk to your veterinarian about pros and cons as well.

I normally recommend neutering medium to large breed dogs like Australian Shepherds at the age of 10-12 months. It's true that testosterone is important for proper development of the bones and joints, so neutering at an earlier age can sometimes increase the risk of orthopedic problems later in life.

The biggest concerns with large breed dogs are neutering them before their growth plates have closed (as I'm sure you have read). At one year of age and 65 pounds, it sounds like Limon has stopped growing, so we do not think you will get any further benefits to his joints waiting any longer than you have. Unfortunately, there isn't a lot of great research about this subject yet, but I also neutered my dog at 1 year of age because I didn't think there were any benefits of waiting any longer than that in a large breed dog. I hope that was helpful! Thanks for using Petco Pet Education Center, formerly Petcoach.

By convention, the general recommendation often 4-8 months, though early spy/neuter is common especially in shelters. A male dog who reaches sexual maturity before being neutered will grow into a “stalkier” build typically. There are also studies suggesting that waiting to neuter decrease the risk of knee problems and some types of cancers. However, he is also more likely to develop behavioral problems. With ages over 2, unneutered dogs are at a MUCH higher risk of overall health problems. I’d recommend talking to your vet about what their thoughts are. I don’t think there’s any significant difference in early neutering and neutering at 6 months of age. Here’s a couple of articles to consider: http://www.vrcc.com/oncology/does-early-castration-increase-the-risk-of-cancer-in-dogs/ https://www.petcoach.co/article/early-spays-neuters/ For what it’s worth, I don’t think it’s wrong to do it at 6 weeks and I don’t think it’s wrong to do it at 2 years. I DO think it’s wrong to just decide to NOT do it all together. I hope that’s helpful... I realize it may just muddy the waters more for you, and I apologize! Talk to your vet about what he or she recommends and the two of you can come up with the best plan for Diggy.
