Why does vet require puppy to be 6 months of age to be neutered?

I have a yellow lab puppy that I wish to have fixed, as there is no reason he not be. I know the benefits, and really don’t see a down side. My vet requires the puppy be 6 months old before he will neuter him, why?

Some vets are like that.. I am not sure why.

it’s safer for the dog to be 5 to 6 months old when they have to put him under for the operation.

That’s odd. Most vets encourage early neuters – maybe he just believes that it’s just too early, though I’ve known dogs who were neutered at eight weeks with no ill effects.

In part to make sure he is healthy and able to withstand anesthetic and stress. And also to have a better, larger area in which to work in. The larger and older the puppy to easier it is to work with his bits and pieces.

So that the testicles are descended and he is able to snip them off easily without invasive abdominal surgery to pull them down. Castration in males is easy once the testicles are descended – and males are rarely sexually mature until after six months of age, so it is a good time to neuter them. Hormones peak at around seven or eight months of age for most male dogs – if his testes have been removed prior to this, you will be making life much easier for both of you.

You can wait til they are 6 months of age.. You can get them done much earlier than that.. Some vets have no experience with surgery on a young puppy, so they insist you wait.. Plus they can charge you far more if you wait.. If I get a puppy done at 8 weeks of age.. It costs $ 45.. If I wait til they are 6 mos plus, then it costs $ 150 Plus to get them neutered.. Huge difference.. If you want it done now, find a vet that is experienced with surgery on young puppies.

It’s a subject of debate. A puppy does not need to be 6 months old – many shelters and vets spay as early as 2 lbs and 8 weeks old and the AVMA condones this practice as safe. Dogs under 6 months in research recover faster from surgery than those 6 months and older. There is conflicting evidence about whether there are potential developmental issues related to early spay/neuter. Most professionals agree that shelters should do it because the vast number of adopters that don’t return later even if they promise to. Some vets (but not all) stick to the 6 month rule for dogs because females rarely go into heat before that age and most males don’t develop marking, wandering and other unwanted behaviors before that age. But on the dog’s 6 month birthday, I’d have an appointment lined up and not wait a minute later.

Ask him why. Spays and neuters can be done much earlier. However, some vets would rather wait. There are some people who will wait until the age of 2 to neuter a male. I would ask your vet why he waits until that age…

Because he is either older or working off old information. Jeuvy neuters have been being done for over 30 yrs with no ill effects and many benefits including quick healing and absolute zero chance of the young pup getting away or an irresponsible owner letting them breed to add to the death toll of pets put to death for lack of homes. Many many shelters neuter kitten and pups by 6-7 weeks and many reputable breeders do so as well. The AVMA is on record as endorsing early age spay/neuter.
As president of the AVMA, I feel it is unconscionable not to use early spay/neuter since it is safe and very very effective in achieving our goals.”

Testicles are dropped in male pups by 6 weeks in the vast majority of cases, one of the criteria of buying an 8 week pup is to feel there are 2 testicles present in the sac. Some do drop later or play hide and seek but are not in the abdomen. Retained testicles do turn cancerous and that requires a major operation. The local GSD Rescue always neuters all pups b4 their 8 week adoption date. And the jeuvy neuters I have seen from 3 mos until 4 yrs old did grow slowly but were tall when fully grown. My Schutzhund class had pups from a litter of GSDs turned over to rescue and I was surprised at their small size at 3 mos until 12 mos then they sprouted until they were tall at the last time I saw them. At the time I wasn’t aware jeuvy neuters grew sloower and grew taller than their later neutered or non neutered littermates. The MinPin Rescue I work with has a 4 mos old pup that was found as a stray and he is due to be neutered in 2 weeks after his staph infection clears and his shots are done. At 4 mos old he is lifting his leg to pee so he has all his hormones despite the fact he has puppy teeth. My last Rott was 4 mos old and lifting his leg as well so dogs do mature at different rates.

That’s the age they are mature. If you wait too long they will start marking their territory.

my vet does it at 6 months because it is easier to work with a larger pet. The animal is larger all over compared to an 8 week pup, plus, knock out chemicals are probably much easier to control on a larger pet.

Female dogs AKA Bitches can properly produce off spring at 6 months of age.Male dogs AKA studs are not sexuality mature till 6 months of age.So it is possible to neuter/spay before that age. but why put the dog through surgery at such a young age when it is not necessary.

Most vets don’t reccommend putting dogs under until they’re older.

A vet in my area won’t fix toy breed dogs until they’re a year old, because he lost a chihuahua once while spaying her. She was 8 months. Go figure.

All vets use to wait until puppies were at least 6 months old, but now they do it when they’re very young. Personally, as a lifetime pet owner, I think waiting until they’re 6 months old is a good idea. Perhaps it hampers their growth or development? I don’t really know the reason some vets would rather they be older, but there seems to be no reason to do it earlier anyway, so what’s the harm in waiting? Could be the anestetic, which can be very dangerous for very young puppies.

Six months is the typical age.

I think it’s because the chances of surviving the operation are much higher.

You need to wait until at least 6 Mon. old because they could have medical problems later plus you need to make sure ho is completely wined from his mother. Also at that age their bodies will be strong enough to handle that situation

It is so that the testicles are fully descended and the operation poses less risk for the dog as it is less invasive.

Some vets however are happy to operate on a younger dog – so it is really down to you.

It’s safer for the dog. If you want to know why your vet does it ask them. They won’t get mad.

When a male puppy is born his testicles are up inside his abdomen, by the time he is 6 months old they will have moved outside of the abdomen and down to be back between his legs. If a vet does surgery before the testicles have descended the surgery is much more involved since the vet has to open the abdomen to get to the testicles. It’s safest for your dog to wait.

As long as both testicles are decended it can be done at any time. If both are not decended by 6 months then they have to go inside to find the one that is not.

All 3 of my males were neutered at 5 months with no ill affects.

Well here are the benefits AND downsides.. the ones vets won’t mention to you. In fact as far as health goes, it’s better NOT to neuter a male dog. ESPECIALLY at a young age. As long as you are responsible enough to prevent him from reproducing…

On balance, it appears that no compelling case can be made for neutering most male dogs, especially
immature male dogs, in order to prevent future health problems. The number of health problems associated
with neutering may exceed the associated health benefits in most cases.
On the positive side, neutering male dogs
• eliminates the small risk (probably <1%) of dying from testicular cancer
• reduces the risk of non-cancerous prostate disorders
• reduces the risk of perianal fistulas
• may possibly reduce the risk of diabetes (data inconclusive)
On the negative side, neutering male dogs
• if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a
common cancer in medium/large and larger breeds with a poor prognosis.
• increases the risk of cardiac hemangiosarcoma by a factor of 1.6
• triples the risk of hypothyroidism
• increases the risk of progressive geriatric cognitive impairment
• triples the risk of obesity, a common health problem in dogs with many associated health problems
• quadruples the small risk (<0.6%) of prostate cancer
• doubles the small risk (<1%) of urinary tract cancers
• increases the risk of orthopedic disorders
• increases the risk of adverse reactions to vaccinations

While pediatric spay/neuter on animals between 8 and 16 weeks of age is widely accepted as safe, your pet is best protected from communicable disease transmission when it is at least 18 weeks old and has received its full vaccine series from a veterinarian a week or more prior to surgery.

Some vets do this so they can charge more. They more the dog weighs the higher the price. If you wait untill he is atleast six months he will be at least halfway grown. Take him to another vet and get thier own opinion. The rule of thumb at TWO vets in my area is two pounds and at least 8 weeks. Both vets like to wait to do small breeds (chihuahaus, etc.) untill the are six months thou. My male was neutered at 14 weeks and my female spayed at 12 weeks.
