Neutering stunts growth?

I've had two people tell me now that neutering can stunt a dog's growth if done before 2 yrs of age while articles on the next say they actually grow a fraction of an inch taller after neutering.

This is all up in the air honestly..... I believe it may slow down the growth.
Genetics play a huge role on what the dog will be, but at the same time taking testoterone away too young, before 6 months will stunt growth.
Google the search, and you will find many different answers

Well he's 11 months old now. So basically he's just going to fill out.

As he has been having difficulties with other dogs, I would suggest you neuter him. He's already a large dog and perhaps reducing his testosterone level will help him with his socialisation? Just a thought.

I had Harley neueterd at 11 months, and he is still growing. Alittle too much for his britches actually. If you are not showing him, you may want to neuter him, because Mals, alot like rotties can become very territorial. you will have alot easier time training and controlling once his babies are gone:p
Harley does not even miss them

I was showing him but my neighbours' dogs' safety is more important to me.

I socialize him with females for the time being until he's neutered.

This has been a cause for much debate. Some people believe that neutering/spaying affects the growth of an animal, other people do not. Puppies and kittens have been neutered much younger than 6 months and they grow normally. Genetics is the main contributer to how an animal develops. Yes, I also do believe that the environment also plays a factor to their growth. I personally don't believe that neutering/spaying makes a huge difference on the growth of an animal.

I had Misty spayed at 6 months of age. She had not finished her growing by then. She matured to a height of 15.5" and a weight of 32lbs. Slightly bigger than the beagle standard.

Honestly, I don't think it makes that much of a difference either way . . . Genetics is the main factor. If neutering does have an effect, it's probably not more than a few inches more or less at most (depending on the breed), so does it really matter? :) The dog isn't going to be thinking, "Oh no, I'm an inch less than breed standard! MY LIFE IS NOT WORTH LIVING!!!1" ;) And neutered dogs can't be shown anyway, right? (I always thought that was stupid.)

Dogs have to be intact for showing because they wat to see the full dog, au natural as they say. But the do have at some clubs where neutered dogs can show. Altered class as they call it.
Another reason for intact dogs in the ring is because 90% of the time in the ring, they want to breed the dog, and they have to see best dog wins the right to mate. Not many show dog without intent to breed. Although I was one of them, I just had fun with harley. I am not doing it anymore, so I neutered him:pawprint:

I had Charley neutered at 6 months and he grew a little afterwards (There isn't much to him to begin with).

That last hormone kick might cause a slight bit of extra growth, or maybe more in the 'filling out' department, but if he hasn't really added any inches to his height, I can't see getting him neutered making a very big difference.

The neighbour had her cat neutered at 6 months and he doubled in size between then and finishing growing...

My old vet did not want to neuter my cats before 6 months,she said their heads don't grow as big if neutered early.
I tended to believe her,because the cats at humane society,who were neutered later in life,all were huge beautiful cats with big heads.
But then again,it could be genetic.

I've actually read a scientific paper on this subject, but since it was biased towards neutering (or altered to be biased towards neutering) it really didn't say anything useful.

My understanding is that neutering, before an animal is mature, means that the growth plates on their long bones (such as legs) do not close as quickly, and that neutered dogs actually grow taller.

However, due to lack of testosterone, they do not 'fill out' with muscles and so tend to stay very gangly their whole lives.

But I think this applies mostly to dogs neutered before puberty. I don't personally think there is any real affect for neutering once the dog is older.

I don't believe that there is any scientific proof that fixing a dog will do anything to the growth of a dog

Ooo... Who posted it? Dang... Somebody posted research on here fairly recently that proved that neutering early actually caused doggies to grow more. It was quite logical. The sex hormones close the growth plates and neutering early, pre-puberty, means the sex hormones never develop to the concentration that they would post-puberty intact. Less sex hormones, mean the plates stay open longer, which means the dog grows for a longer period of time.

And I have also heard that smoking stunts your growth...:rolleyes:

Sorry,I had to throw that in.....:D

I definately don't believe it.I do believe that "alot" has to do with genetics.All my dogs have been done at 6 months(had to,breeders contract)..And they still continued to grow till about 2 years of age and fill out.

I have seen quite a few GSD's that were of different sizes.Either a few inches taller or smaller.

The breed standard for a Mal should be 25" at the shoulder and a solid 85lbs

As for cats getting done early,my male Casper was done at 8 weeks(2 years old now)and let me tell you,he's a big boy with a big head....:D

I always snicker when I hear that stat. Zeus is 28" at the shoulder and 100 lbs. :p

His dad is 27" and 120 lbs (not fat). His mother is 26" and 92 lbs.

I just remembered, I have a perfect case study staring me in the face that I neglected to look at.

Zeus' brother, Xander, was neutered at 6 months. Zeus is still intact.

I guess neutering doesn't stunt your growth. :D

Perhaps this is in reference to the big jowles or 'neck ruff' that mature male cats develop. Neutered cats stay sleeker as they do not develop this male charateristic. I don't know if the actual head (ie skull) grows bigger or not, but it would be an intersting study.

This is funny, as I was going to ask everyone's opinion about having animals fixed. I had another person said that if you wait until they are a few years older, the dog will become very lethargic. He used thier two dogs as an example, one was done while young, the other was done after a couple of years. The one that was done older wasn't as rambunctious afterwards, and I know I've often heard that said about cats. Daisy was done at 6 months (I was also told most vets won't do it before then, which I think is kind of mean. I mean, they are just starting to figure out what that stuff is for, then *SNIP* it's taken away from them!;) ), and if she was any more hyper, we'd have her on some sort of puppy valium.

Well.. with all due respect, that's not accurate. Since the theory is that the dogs grow longer, not faster. And at 10 months old, neither pup is full grown yet :) And it woukld probably only be an inch or two difference, which might not affect how much they weigh.

Genetics is still the biggest part by far, along with diet.

Schwinn, I had my 3 year old dobie neutered (as soon as we could) and there was no difference. In my experience, the older the doggy, the less effect it has.

Harley has not lost his edge so to speak, he was done 2 months ago, and is now 13 months. Still as energetic as he was before.

True. I guess we'll see what happens in the months that follow.

Both my dogs were done at 6 months and Travis weighed in a 120lbs and was about 30inch at the shoulder, he was a BMD x GSD so I'm glad I got him done when I did, could you emagine if I didn't he would have gotten bigger. Tucker is a BC and weighs 55lbs and is 22 inch at the shoulder which is a bigger border collie but in the guide lines for his breed. I don't think it really makes that much of a difference in size but it does in mannerizm.

This is an interesting theory,
as I have always heard the opposite, that neutering often
makes male dogs and cats much larger!!
Strange, I have never heard of it stunting growth,
and have known many people who neuter their animals
quite young so they will be larger.

Maybe it's just attitude. I mean, I know if i was neutered at 21 (3 in dog years), I'd probably figure there was nothing left to live for and become lethargic too...

I heard that as well. Something about not receiving the hormone to close the growth plates properly.

I'm neutering Zeus in 2 weeks.

my GSD cross was done at 3mths of age. she grew just as big as her mum and now is 34kg and quite tall. i wonder if this is jsut one of those - 'i wanna feel better for not desexing my dog so this sounds assuring' theories.

desexing saves lives........
