I would do it once he’s a year to 18 months old. If you are responsible with your dog I don’t think is it a huge deal to keep him intact, but I personally would still have it done. Dogs can go nuts trying to get to a female in heat, breaking through doors, fences, etc. It’s just not something I would want to risk.

@MrsPanda99:  Four months ago. There is no concrete information that it effects the size of the Boxer, and conflicting information favors both for growth. Boxers are very dominant dogs, and if he is showing these tendencies..get him snipped.

It will not affect the energy level. At all. There is no reason to wait. 

I have two wonderful Boxers 🙂

My dog was neutered before we adopted him and we adopted him when he was 13 weeks old. He’s grown just fine but he has a puppy-dog face. He’s some kind of shepherding dog mutt and is currently 45 lbs after a weightloss regimen. He was close to 60.

I think you should definitely neuter, but there’s no reason I can think of not to wait until he’s adult, which on a dog that size is probably 2. Have you asked your vet?

Our dog was neutered when he was 7 months old.

@MissFemmeFatale:  Have to agree! We waited till 9 months for our two and wish we’d done it sooner! They’re a lot calmer and more respectful now!

There are pros and cons to spaying and neutering.  There are health risks to neutering, but there are also other health risks to not neutering.  

My feeling is it is usually better to do it sooner rather than later, especially if you intend to do it eventually.  Waiting longer, IMO, is just increasing the risk of an “oops” litter.  Even neutered males will react to females in heat, suddenly becoming idiots and forgetting all their training.  If your dog is unneutered, it will only increase that desire to roam and to mate.

The problem with citing one article is most of the references in the actual article cite one specific study. In science, one study with findings does not make scientific truth. The study conducted on bone cancer was conducted in 1998, which leaves it over 15 years-old. Your boxer has a .3 percent chance of developing Osteosarcoma. Even if neutering him brought that figure up three times, it would still be less than one percent.


Furthermore, a dogs size is determined mostly by genetics, not hormones. Even though you are reducing the amount of testosterone in the dog’s system, it will only slightly effect muscle mass and not the frame or size of the dog.

You are reading the wrong research if you don’t believe neutering a dog is more beneficial than not.

I don’t think we really know for sure the impact of age at neuter on cancer risk or orthopedic promblems.  There is some evidence that dogs prone to cruciate ligament injuries may benefit from neutering at a later age (again, not concrete).  If I had a large-giant breed male dog, I might wait until one year to neuter.

@MrsPanda99:  As soon as possible otherwise the behaviour will be out of habit as it has developed. Ours was done at 2 and a half, which stopped some of his dominance but some things by that age he had learnt and was therefore not going to stop doing them.

We had a great dane/bull mastiff that developed testicular cancer. He was in a lot of pain, the poor guy. He died a slow, painful death, but he lived a very long life (His death was unrelated to the cancer, but it did hurt him terribly.)

My current dog is a black lab that was neutered at 2 months old by the Shelter I adopted him from. He is 90 pounds and his head is at my waist (I am 5’3″) so he is a living testament to neutering a dog not affecting their growth.

I’d neuter all of my dogs purely because I don’t want them to suffer cancer like Claude did. In his end days, he was in enormous amounts of pain even with the pain killers he was doped up on. Putting him down (He was 16 or 18 at the time) was the best thing for him.

Not to mention if your dog has any aggression issues (which can develop later in life), neutering will help curb those issues.

ETA: Dogs get out of your yard. Dogs get into your yard. Accidents happen. Please be responsible and neuter him. Thousands of dogs are put down every day because shelters can’t afford them and they’re overcrowded.
