What Happens If I Dont Neuter My Dog?

Actually testosterone has been linked to protect dogs against cancer in a couple of scientific studies. Also, bone cancer is more common in neutered dogs than in natural dogs. Testicular cancer is a possibility, yes, cancer that actually affects only less than 1% of the males.
Now I am only going to talk about male dogs, since studies on female dogs are usually inconclusive.

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

Now you choose: Do what your "vet" tells you it is best for your pet, or do what science (and not politicians and business owners) tell you about neutering male canines.
If you want to read the study follow the source  www.naiaonline.org it is all about population control do not leave your dog abandoned
all day long. I never leave mine, not even for one minute. Neutering is
therefore a bad excuse to practice eugenics at an animal level.There are tons of OPINIONS on the subject but only science can determine which of those opinions are facts or myths. I, personally, opt for science, how about you?

I completely agree with the anti neutering comments.  It's cruel and has serious side effects down the line.  It also creates pain , any operation leaves  physical scars.  Neutering is  a simple way for humans to deal with their pets but it isn't in the best interest of the pet.  I believe some vets know it's wrong but see it as easy money while others have been indoctrinated and mindlessly just follow along.  My Dogs will never be neutered and yes it's harder because when they have their periods it's a mess, however, I am not going to mutilate them because of convenience. If neutering really has such health benefits , why don't we all do?   Have our balls chopped off and uterus yanked out?  Why stop there remove all organs that could possibly become cancerous.  Many European countries have laws against neutering.  It is seen as barbaric animal cruelty and these countries have fewer animals put to death each year maybe it's a different perception and value system.  An animals body part isn't disposable and neither is the pet.  If the best interest of your pet isn't top priority in your life then don't get one. You'll be doing them a favor.

I must really agree with "TheThinker" on this one. Just because its politically correct it doesnt make it correct. And those who tend to state there are medical reasons to have your dog neutered does nothing but prove their own ignorance of the subject. Neutered male dogs display a fourfold increased incidence of prostate cancer over intact males. And lets not forget that neutered dogs and cats of both genders have an increased risk of obesity. Theories for this include reduced metabolism, reduced activity, and eating more due to altered feeding behavior

Haha no joke.  Shoot I'm just going to chop of my childrens limbs cause they might get out of control.

I haven't had my 4yr old mixed lab neutered yet nor do I plan to.

I have a saint bernard who is perfect;  He is sweet, smart, 5 months old, potty trained, has no aggression at all.  He is by best friend and I love him.  Now I am faced with this time line that I have to get him neutered within the next 2-3 weeks (before 6 months of age).  I am stressed, scared, and really don't know if I should neuter him.  Is it wrong for me to neuter "brutus"?  What bad things could potentially happen to him?  I love my dog and I want to do what is best for him.  Any feedback on this would be greatly appreciated...

Yes its very wrong and its in-humane to do this don't let her or him go through it!

No, neutering a dog (male's especially) is not humane nor good for the animal, and not just for reasons such as muscles not developing properly or quadrupling certain cancers(which are valid reasons on there own) it is wrong because it is only for the convenience of the owner, and if a owner can not keep there dogs from mating they probably shouldn't own a dog in the first place.

And to the people that said that neutering a dog stops behavioral problems such as aggression, aggression in dogs (or males in general) isn't a behavioral problem, that is how males naturally are. Its like saying you should put your child on ritalin to cure their "behavioral problems" when all you are actually doing is turning them into a mindless zombie, as opposed to being a good parent(or owner) and teaching them right from wrong.

(sorry for my poor english)

I think that you should spay and neuter unless your willing to care for and/or give 3-10 puppies a good home. It isn't just about the dog and the way it acts it's about it's unborn babys and their Standard of life. Always neuter unless you are a proper breeder thats wishes to carry on the breeds bloodline, behavior and looks so others may enjoy their company.

Well I know a lot about dogs. If you don't neuter your dog it may have puppies, but you can stop that from happening by keeping it away from male dogs if its a girl when shes in heat or keeping  him away from the females in heat. If you our dog does have puppies then the gene pool can certainly benefit. I do believe for medical reasons if your dog needs to be neutered or spayed, for example if he/she is from a puppy mill(go to prisoners of greed to learn about what they are)  which over - breeds dogs. It can also help him/her develop into an adult. - YL

NEUTER YOUR DOG! If you don't spay/neuter your female dog and she gets near a male, she could easily have babies. If you don't want puppies, the puppies can be thrown out, just producing more homeless puppies. NEUTER YOUR DOG! For the good of a dog's wellbeing!

It is certainly not wrong to neuter your dog though some people do think that it is cruel because you are taking away the dogs manhood in a sense. However it can actually help the dog in a number of ways.

In some breeds such as the Saint Bernard, by neutering them you could actually be decreasing their chances of developing cancer and other health problems. The main reason people neuter their dogs however is to stop various behavioral problems. Problems such as aggression, constant excitability and marking their territory can be frustrating and there is a chance that neutering the dog can help. Also many dogs are constantly humping things and that is a sign of sexual frustration and by neutering them it can take those feelings away.

However, overall neautering can help but it does not always work to take away behavioural problems. It is certainly not wrong but it all depends upon your own opinion.
