When should I spay my female dog? We recommend waiting until your dog is at least over 6 months and likely even older for larger dogs. The benefits are much more pronounced in larger dogs, but there is not a lot of difference for lap dogs.
There are some old wives' tales that a dog should go through at least 1 heat cycle before she's spayed. This just isn't the case. Studies have shown that the risks of mammary cancer and urinary incontinence are higher if you wait to spay your dog after she's gone through 1 or more heat cycles.
It's generally recommended to spay puppies between the ages of 4 to 6 months, says the American Animal Hospital Association (AAHA). By that age a female puppy's sex organs are fully developed but she hasn't yet experienced her first heat cycle, during which she could become pregnant.
Spaying your dog too early can result in health problems later on since her hormones should have some time to work. Early spaying can increase the risk of hip dysplasia, torn ligaments, bone cancer, and urinary incontinence.
Due to the prevention of sudden hormone changes, a female dog should return to her normal behavior within the first three weeks after spaying. However, spaying does not change your dog's personality. She will not be any less hyper or aggressive after spay surgery if those are her normal personality traits.
The discomfort caused by spay or neuter surgeries usually only lasts a few days and should be gone after a week. If your pet is experiencing pain or discomfort for more than a couple of days you should contact your vet to get further advice.
To be clear, the question here is whether or not to spay early or after the first heat cycle. Because of significant risks of pyometra (uterine infection) or mammary cancer late in life we recommend that all female dogs not intended for breeding be spayed before their second heat cycle.
Removing Hormones can be of Benefit
Another reason veterinarians settle on the six-month recommendation is that if a pet is not going to be bred, spaying a female dog before her first heat cycle has a significant benefit in terms of reducing the risk of mammary cancer.
Small breed dogs (under 50 lbs projected adult weight): There is no question here at all, males should be neutered at 6 months of age and females should be spayed prior to their first heat (5-6 months of age). Large breed dogs (over 50 lbs projected adult weight): This is where things become a bit trickier.
Estrus is the stage when the dog can become pregnant. Although this can vary with each individual, on average a dog will be in heat for 1 ½ to 2 weeks but this can be shorter or longer.
The drop in estrogen level can become an immediate reason why the dog may seem to be calmer, simply because of its effect on the female reproductive cycle. But Neutering or Spaying is simply not the answer to your dog's aggression problems. In many dogs, spaying has definitely helped ease their behavioral issue out.
Basically, we are seeing that delaying spaying and neutering until after maturity lessens the risk of hip dysplasia, cruciate ligament tears, other bone and joint abnormalities, and some cancers. Behavior disorders, including aggression and noise phobias have also been related to hormone status.
Can Spaying or Neutering Make a Dog Less Hyper? The short answer is that no, your dog isn't likely to be less hyperactive after getting spayed or neutered. It won't change their personality much, if at all.
Spaying: A spay procedure should be done at 4-5 months old. This is before your dogs first heat cycle, which typically falls around 6 months — this helps decrease the risk of serious health issues, such as mammary cancer. Neutering: A male dog should typically be neutered during the same 4-5 month period.
Austad and Hoffman say spayed and neutered pets live longer, healthier, happier lives because they have fewer behavioral issues and they are less susceptible to infections, degenerative diseases, and traumatic/violent causes of death.
Dogs who are spayed/neutered too early have an increased chance of developing undesirable behavioral issues such as phobias, fear aggression and reactivity.
Either way, it is very important that you limit your pet's movements during the 7 to 10 day recovery period, as strenuous activity, such as running, jumping or playing, could disrupt the healing process and even cause the incision to become swollen or open.
Your pet needs to be kept in an indoor crate/ kennel for most of the day and night for the next 10 days. The time of highest risk for the sutures breaking down is 3-5 days after surgery.
While some dogs are able to tolerate pain more than others, don't be surprised if your dog whines or whimpers after being spayed. It's perfectly normal for dogs to whine after being spayed.
Desexing will not change your dog's personality. Male and female dogs that are desexed have a nicer temperament as they are not as driven by their hormones and make much nicer family pets.
She may cry or moan a little, and might just feel like sleeping. It's important to let her rest, keeping her still will be essential for an uneventful recovery. It often takes a day or two for pets to feel like themselves again. It can also take a couple of days for them to pass faeces.
Heat usually lasts between 2-4 weeks. Early in the cycle, a female dog may not be receptive to male dogs, although some are receptive through the entire cycle. It can be shorter or longer and you'll know the cycle is over when all her vulva returns to its normal size and there's no more bleeding or discharge.
