Spaying or Neutering Your Dog

The only way to be sure your dog doesn't produce unwanted puppies is to get your female dog spayed or your male dog neutered (castrated). Intact male dogs and bitches in heat have an uncanny way of finding each other, and breeding can occur in a snap.

Spaying involves the removal of both the uterus and the ovaries. Castration refers to the removal of a male dog's testicles. The term neutering is a general term to describe either spaying or castration (but you may hear the terms neutering and castrating used to mean the same thing).

In addition to preventing unwanted puppies, neutering your dog has many benefits:

  • Female dogs who are spayed prior to their first heat cycle (which usually occurs between 6 and 9 months of age) have a significantly reduced chance of developing mammary (breast) cancer compared to dogs who have had even one heat cycle.
  • Spayed females can't develop pyometra, an infection of the uterus that can be quite severe and can even result in death.
  • Spayed females tend to have more even temperaments and do not go through the hormone-induced mood swings that intact bitches sometimes have.
  • Neutered dogs often are better behaved than their intact counterparts. Not only are they less likely to roam (visiting neighborhood females is a major reason for roaming), they are also less likely to mark their territory by urinating in the house (testosterone is one of the major drives for this dominance-related activity). In addition, neutered male dogs are much less likely to be aggressive toward other male dogs. These behavior benefits are particularly true if you castrate your dog between the ages of 9 and 12 months, before he becomes sexually mature and develops bad habits.
  • Neutering prevents the development of prostate problems often seen in older dogs.
  • A neutered dog won't develop testicular cancer, a common cancer of older, intact male dogs.

Male dogs who lift their legs to urinate don't leave urine burns in the middle of the lawn, because they usually urinate on trees, fence posts, and other vertical objects around the perimeter of the yard. If you prefer that your male dog lift his leg rather than squat to urinate, wait until this habit is well established before getting him neutered.

Many people think their dogs will get fat if they are spayed or castrated, but this isn't the case. Neutered dogs frequently don't need as much food as their intact compatriots, but there is a simple solution: Don't feed them as much.

Depending on your locale and the veterinarian you select, it costs between $50 and $120 to castrate a male dog and between $75 and $140 to spay a female dog. For people on public assistance or with lower incomes and for seniors on fixed incomes, spay/neuter clinics are held in most towns and cities. These usually are sponsored by animal shelters and veterinarians as part of their ongoing effort to control the local pet population. To find out when these clinics are held in your area, contact your local animal shelter.

For the first couple of days after surgery (whether for castration or spaying), your dog should rest and should only go outside to the bathroom. For the next week, mild exercise such as on-leash walking is all right. About ten days after surgery, the veterinarian will check to make sure the incision is healing properly and remove the sutures (or check on self-dissolving sutures).

    My dog was neutered yesterday, and silk sutures were used. He will have the sutures removed in 10-14 days. However, the bonnet-collar is not supposed to be removed until the suture removal visit. It seems impractical, is it necessary to leave the collar on for the full 10 days?

    Sally, I just had my dog neutered today, and he also has the collar on. Poor thing I feel sorry for him. I don't know if I will be able to keep it on him the whole time. I see it has been a few weeks for you, any advice?

    Some parts of this article are borne out by Veterinay research but it is simplistic and omits to address the many detrimental aspects of neutering. For example there is a 4 times greater risk of prostate cancer (much more serious than testicular cancer) for males, chances of increased aggression in females, orthopaedic disorders, hemangio sarcoma and a host of others. Health, behavioural and societal concerns are addressed in the following two Veterinary research articles. Both suggest the reader consider all the good and bad points of neutering before deciding what is best for them and their pet. http://www.naiaonline.org/pdfs/LongTermHealthEffectsOfSpayNeuterInDogs.pdf Long-Term Health Risks and Benefits Associated with Spay / Neuter in Dogs Laura J.

    Does a neutred or spayed dog after many years of being fixed still cause dead spots in grass?

    I wish it was that cheap. I just had my dog neutered here in Canada and it cost me $250.00. Females cost another 30. My dog was considered small, the price goes up by the weight of the dog.

    There is an alternative for the collar, my dog was very uncomfortable with it so instead i put a T-shirt on her that is long enough to cover the incision so they dont lick it. For us this worked perfectly but i am not leaving her alone not even one second until she is completely cured! I had permission from my job to stay with her! :-)

    we have two 18 mo old great danes. female spayed and male intact. He is going crazy trying to impregnate her. She seems to be giving off a scent that isdriving him crazy to connect with her. He's licking her all over and attempts to mount her 24/7 if we are not on him. Is this correct after being spayed? I thought she would not be attractive anymore.

    How old is this article? "Depending on your locale and the veterinarian you select, it costs between $50 and $120 to castrate a male dog and between $75 and $140 to spay a female dog" - that's COMPLETELY WRONG. On the East Coast its over $400. Also, there is NO evidence that neutering makes a dog calmer or less aggressive. In FACT, a spayed bitch is MORE likely to bite. (U of Penn Vet study).

    So I have a 110lb chocolate lab whose 3. He doesn't walk great on a leash & sometimes runs off, but other times he's okay off the leash but can also get WAAY excited. Sometimes he just doesn't listen to. He's kinda like Marley, but not THAT bad. Anyway we just moved & theres been a female Rottweiler visiting lately but now is locked up across our alley & he's been going absolutely ballistic trying to go see her, he hasn't been eating much, & he's been howling like crazy inside & outside for her.. He's never been this bad or howled like at all.. He also urines on EVERYTHING when we go for walks. Do you think if I get him neutered that it will fix a majority of these problems. He's a big mama's boy & I don't want to change him other than his bad habits when he has them. I also feel like I'm robbing him of his manhood & would like to think I could breed him out someday but.. Do you think it would be the right thing to do?

    "Intact male dogs and bitches in heat have an uncanny way of finding each other, and breeding can occur in a snap." Excuse me? "Uncanny"? As in, magical? Eerie? Not likely in a real or responsible world. The first rule of pet ownership is not to let your animals run loose, and if you follow that, you don't really need to spay or neuter. Veterinarians would prefer that you do, of course, since they have car and house payments. But so do I. And I don't appreciate being jerked around by magical thinking when I'm perfectly capable of taking care of such incredibly simple matters as not letting my animals reproduce. They don't need surgery to prevent it--only my keeping the doors closed. Duh!

    I got better idea. Why not spay and neuter all man ,women and children in the US so they all can lower they chances having breast cancer or prostate cancer since the odds of getting one is pretty much the same as in your pets!? Enough of that mambo jambo about spaying/neutering poor animals.Guess what,your vet doesn't give a damn if your dog will die during/after the procedure or will develop health problems(and she/he will,i can assure you),all they care is money,unfortunately like most people living in the US.What happened to your reasons and senses,stop being robots and do what media/vets tell you to do.Have your own head and think for yourself for once!What about all those wild animals,how come they do not need to get spayed/neutered and they live happy,healthy lives,ah? Just think for a second!!!!!!!!!!! And if your excuse is overpopulation of cats/dogs then we should spay/neuter or better yet euthanize everyone in China,Africa ,India and US cause it is not enough natural resources on this planet for all of us!

    Hi - about the e-collars for your dog after castration or spaying - if you're hanging with your cat or dog and can keep a close eye on them then you should be fine to take it off. But if you're not able to watch them and you've seen them licking their wound when the collars off it's best to leave it on. They can aggravate and irritate the wound, and even pull out stitches which will cost you time and money to go back to the vets to get it fixed. Better to avoid in the first place! I agree that e-collars can be a real pain - I had a St Bernard and when he was castrated the size of the e-collar he had to have was enormous! poor thing kept bumping into things! But better to have it on if the alternative is him keeping his wound from healing. Hope that helps. And in our defence I know there are some vets who are mainly interested in the money, but most of my class of 100 students aren't, and our professors aren't. Nearly all of the vets I know charge far less than what they 'should' based on time, costs, and expertise. It's easy to make sweeping judgments if there's misunderstanding or poor communication - something we're all trying to remedy.
