Should I wait to neuter my 1-year-old large dog for bone health?

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.

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.

The veterinary world is still undecided upon the benefits of waiting until after a pet has had a heat cycle relating to the ligaments. For smaller breed dogs, there may not be benefit. We do know there is a benefit as far as cancer reduction in dogs spayed before their first heat cycle. It is true that spaying a pet will decrease the sex hormones and this affects the joint physis. This however tends to be more of a concern for large breed dogs. At only 6.5 kg at four months old, Luna is not very likely to be a big dog. For the most part, when waiting until later to spay or neuter a pet it is involving dogs who are expected to be 34kg or above. I recommend to discuss your concerns with your primary care veterinarian as they will be the best to advise you. In general, maintaining good health of the joints involves maintaining a healthy body weight and feeding an appropriate food. Luna should eat a puppy food until she is about a-year-old. I hope this answers your questions and please feel free to post any additional questions.

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.

Great question! The studies about neutering too early causing problems for growth and hips are varied, and there's no consistent evidence yet about this effect. I personally recommend neutering after six months of age and before a year old. You can wait to get Oliver neutered until he is closer to a year old, at which point he will have done a majority of his growth. I hope this helps!

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.

When Boomer is about 12-14 months old it will be safe to get him neutered. Yes, it is better to wait with castration until he is fully grown. There is some scientific evidence that too early castration predisposes to bone maldevelopment and fractures.
