Can A Neutered Dog Still Lock With A Female

Depending on how long ago your dog was neutered, yes he can still breed a female after neutering. However, even if he has no sperm, a neutered male dog can still get an erection and theoretically tie with a female dog. This will not result in pregnancy if it has been more than a month since he was neutered.

How To Prevent Pregnancy In A Dog In Heat

What can you do when a dog is in heat to prevent pregnancy? Try these tips:

  • Watch her closely. When a dog is in heat, her only thought is to breed, and she will often do whatever it takes to find a mate. Its important to keep her supervised at all times or contained in a crate or other secure enclosure that she cannot get out of and other dogs cannot get in. There have been reports of dogs climbing fences to escape and mate, and even getting pregnant through chain link fences, so make sure that enclosure is secure!
  • Keep male dogs away. If you have male dogs that have not been neutered, they need to be kept separate from the female dog. Its best if you can board the male dogs or have them stay at another house during the heat cycle. If thats not an option, make sure there are two barriers between the dogs at all times.
  • Consult your vet in emergencies. If your dog accidentally mates during her heat cycle, there is a morning after injection that will terminate an unwanted pregnancy.
  • Close the windows. Male dogs can detect female dogs in heat from over a mile away. By closing the windows, you contain her perfume to the house.
  • Take caution with walks. Its not recommended to take dogs in heat on walks, because of the risk of attracting male dogs. If you must take her out, make sure she is on a secure leash, and bring a spray bottle filled with water to ward off any would-be wooers.

Can My Dog Go In Heat After Being Spayed

After having your female dog undergo surgery, the last thing you would expect is your dog going into heat after being spayed. Yet, it’s unmistakable, you dog is having a bloody discharge and swelling just weeks or months after the spay surgery, and on top of that, she is also attracting males, just like when she was going into heat. What is going on? Well, start off by taking a deep breath, you are not imagining things, dogs can go in heat after being spayed and there is a logical explanation. If you are noticing any discharge from your female dog after being spayed, it’s a good idea to call your vet and have your dog seen sooner than later, in the meanwhile, here is a quick rundown on what may be going on.

The Purpose of Spay Surgery

A dog’s spay procedure, is medically known as ovariohysterectomy.

For those interested in the origin of words, we can deduce that the word ovario derives from the Latin wordovarium meaning ovary, while the word “hyster” is the Latin word for womb. Then, we have the suffix “tomy” which means “to cut.”

Put these words together and you’ll get the surgical removal of the uterus and ovaries.

A female dog’s two ovaries are responsible for producing eggs that are meant to be fertilized. Those ovaries also secrete female hormones.

A dog’s uterus instead is meant to carry puppies. Once a dog’s eggs are fertilized, they travel to the uterus so that they can implant and start developing into puppies.

Your dog may develop signs shortly after the operation, especially if she was already in heat. Signs may be cyclical and resemble a normal period of estrus. Try to see a veterinarian during the time your dog is exhibiting symptoms:

  • Swelling of the vulva
  • Increased licking of the vulva
  • Vaginal bleeding
  • Standing to be mounted


There are four periods to a female dogs reproductive cycle. The first two constitute the fertile period of being in heat:

  • Proestrus the pre-mating period which lasts for 7-10 days, symptoms include swollen vulva and vaginal bleeding
  • Estrus the mating period which lasts up to 10 days, symptoms include flagging and attempted mating
  • Diestrus the period when your dog is either pregnant or resting between mating cycles, it can last from 10 to 140 days
  • Anestrus the non-fertile dormant period which lasts until the beginning of the next proestrus.

The time between cycles as well as the length of the mating period can vary based on the breed and the individual dog.

Set Up A Comfortable Environment

Create a safe space for your dog to rest. With all the hormonal changes she’ll be feeling, she might want to seek out a quiet place away from the hustle and bustle. You can make this area comfortable by including a cooling mat, which can be especially useful for thick or long-coated dogs. Plugging in an Adaptil diffuser may comfort your dog by exposing her to a synthetic version of the same pheromone that lactating dogs release to their puppies. Have plenty of interactive dog toys and chews for your dog to provide decompression activities.

What To Ask Your Veterinarian

When making the decision about the timing of spay and neuter procedures, it is best to consult your veterinarian and to discuss your circumstances and your individual pet. Here are some topics to cover with your vet during the decision-making process:

  • What are the risks of orthopedic disease and other health problems for your pet, and how might these be influenced by the timing of spay or neuter?
  • Are you willing and able to manage the hassles that come with a cycling female pet or an intact male? This includes, for females in heat, limiting interaction with other animals in order to avoid unwanted litters.
  • Is your pet fully vaccinated? We prefer to wait at least two weeks after the pets last vaccine.
  • Can the operation be performed laparoscopically? Minimally invasive sterilization is an option at some veterinary practices, and at the CSU Veterinary Teaching Hospital.

Talking through the pros and cons of timing for spay and neuter will help you arrive at a decision thats best for you and your pet.

Dogs that aren’t spayed go into heat about every six months. Younger and older dogs tend to have a more irregular heat cycle, and often the size of your dog can affect how often they go into heat. Smaller breeds also might have more than two cycles a year, and larger breeds might have just one a year.

Can A Female Dog Be Fixed While In Heat

Technically, female dogs can be fixed while in heat, however, the surgery is more complicated due to engorged blood vessels and the increased risk of bleeding.

Owners should be prepared to pay a higher fee to fix dogs that are in heat due to the greater technical requirements of the surgery and the increase in surgery and anaesthetic time.

Clover’s First Heat Experience

Preventive Vet office pup, Clover the Portuguese Water Dog, went through her first heat cycle before being spayed. She was almost 11 months old when her owners noticed the first visible signs of heat a few drops of bloody discharge on the floor where she’d been sitting.

Prior to the physical signs of heat, Clover’s owners had also noticed she’d become more intense in her interactions with other females at the dog park, but didn’t show the same kind of attitude with the males she encountered. Once they saw signs of estrus, she stayed home and away from the park. Clover acted a tad more restless than usual, panting a lot and always moving from resting spot to resting spot. Luckily, she had lots of team members in the office to give her pets whenever she asked for them.

For the first five days of her active heat cycle, her heat pants needed to be changed 4 or more times a day, but then slowed to only needing twice daily changes. By using disposable pads inside her heat pants, they were able to cut down on how often they needed to launder the cloth diaper. Once her cycle was finished, Clover was spayed when she was 14 months old.

PRO TIP: Before she went in for her spay surgery, she had practice getting used to the “cone of shame.” By taking some time before your dog’s spay surgery to desensitize them to wearing a cone, you can make the experience much less stressful.

Watch this video below of Clover practicing having the cone put on and walking around while wearing it:

Signs Of Heat In Cats

Unlike dogs, the female cat in heat does not have a vaginal discharge. Her signs are typically behavioral in nature. The more common signs an owner may notice is that she becomes unusually affectionate and quite vocal. She may urinate or spray in the house in an attempt to let local tomcats know she is receptive to mating. She also has a tendency to stick her rear in the air and wiggle her back end when she is petted. If a cat that has been spayed is exhibiting signs of being in heat, this could be an indication there is still sex hormone in her system. If you notice any signs of heat in your spayed cat, please speak with your veterinarian.

Stage : When Your Dog Can Become Pregnant

Veterinary and Travel Stories: July 2011

Once the bleeding stops, the second stage of the dog heat cycle, called the estrus stage, has begun. Many people make the mistake of thinking their dog’s estrus is done at this point, but this second stage is actually when your dog can become pregnant. “This stage, when the blood is done, is when she will accept a male,” Nielsen says. “This lasts an additional seven to 10 days.” During this stage, the vulva will become soft and enlarged.

If your dog is in heat and you do not want her to get pregnant, you should be very careful to keep her away from intact males during this time. “Heat, for both males and females, is very intense and instinctive,” Nielsen says. “They will breed through fences and kennels, and have been known to break out windows and chew or dig through doors to get together. It is a strong impulse.”

Female Dogs & Their Heat Cycle

Dogs come in to heat twice a year. Females that are not spayed are not fertile at any other times only for a week or two during each heat cycle.

The heat is known for its characteristic discharge and the female dogs tendency to flag once she is ready to conceive. During this process she will tilt her tail at a 90 degree angle to the side to invite a male to mate with her.

The first heat can have an onset as early as 6 months or as late as 1.5 years . It is impossible to predict when exactly your female will start her first heat, though usually they start it at around the same time as their mother did.

If you planned to have your girl spayed before she goes into season for the first time and then she surprises you by starting it earlier than expected, you might want to spay her right away to prevent an unwanted pregancy.
