Hello, so I was looking for some opinions on either neutering my male dog or rather doing a vasectomy…
He is not breedable due to his aggressive nature (genetically).
I do not want an accidental pregnancy with my other female.

I’ve read that neutering males can cause diseases and problems later on down the road, I’ve also read the opposite. It can help from cancer. I’ve also read there are pros & cons with neutering aggressive dogs.

Looking for opinions thanks!

Check with your Veterinarian or have him or her consult with or refer you to an appropriate Specialist Veterinarian.

Vasectomy won't reduce testosterone and your male may still try to breed your female when she's in heat. This could cause problems for her. If your male's aggressive nature is at least in part due to high testosterone levels, vasectomy won't help.

Neutering will reduce testosterone, possibly reduce aggressiveness, and probably prevent any mounting of your female.

Again, check with your Veterinarian or have him or her consult with or refer you to an appropriate Specialist Veterinarian.

Because of  the way your post is worded I'm going to assume that you have done some reading on hormone sparing sterilization.  Yes, there are pros and cons to consider.  You have to figure out what is best for you and your dog.  

My two cents:  I firmly believe that it is best for the dog to keep it's hormones.  I prefer female shepherds and have only had one male.  He was kept intact until he developed testicular cancer at age 12.  At that time he was neutered (cancer gone) and lived to 14.  My current female had an ovary sparing spay at age 8 (now 11).  Future females will also receive an ovary sparing spay.

Unfortunately, most veterinarians (at least in the U.S) do not perform the hormone sparing sterilization and don't know much about it.  They are not taught it in vet school and must educate themselves.

I'm not advocating for unnecessary surgery but if you do the vasectomy you can always neuter later.  However once you neuter, that's it.  

You did not state the age of your male. If you opt for neutering wait until his growth plates are closed.

jmoo, but vasectomy will not in any way change your dogs aggressive behavior or prevent him from breeding with your female, just no pups.

Neuter may or may not calm him down a bit, but I'm a former horse/fake cowboy kind of guy, and I've seen a few neutered horses still act (on a much smaller scale) like stallions.

also, I had a Bouvier, that was neutered later in life, and he was a great dog, but still acted the same as before he was neutered.

just from reading your post, and because you asked, I'd probably vote neuter.

I adopted a 3 year old male GSD. About 6 months after adoption, he developed prostatitis. Since I had no intention of breeding him, I had him neutered, as the vet said that was the surest way to cure his prostate troubles.

The ONLY thing that changed was he no longer lifted his leg to pee on the front counter when we visited the vets! And I could safely take him into other people's homes, without any risk of him marking.

When my females came in season, he would mount and tie with them when they hit their fertile period.

Some males will do anything to escape their homes when they smell a female in heat. They will even not bother to come home until she's out of season. In these days of leash laws, this probably isn't as much of a problem as it was years ago, when dogs were often allowed to run loose, but it's still something to think about.

My '2 cents', FWIW - I've owned a male that I didn't bother to neuter, even though he wasn't wanted for breeding. (Physical, not temperament, failings). He never showed a lot of interest in females, even when they were in heat. He suffered prostate troubles in his later years.

I just recently lost another male who I'd had since age 6 years; he'd been neutered, don't know how young. He had never learned to cock his leg, and so always puppy-pee'd for the entire rest of his life. But he would try to hump all his female friends, in or out of season.

Otherwise all mine have been females; but I have worked with a LOT of neutered males, and of those most of them raised a leg (even the one who occasionally didn't), but none pestered bitches, spayed or entire, and all (at least the home-bred ones) were neutered around 8 months of age.

So they are all different. You have to go with what you think is best for you, and your girls, and hope you get the wanted result.
