Do dogs in heat get sick?
A dog in heat can feel mildly ill. However, if they are severely sick, they may have another condition causing symptoms.
The heat cycle begins with proestrus. This is when you’ll likely notice that your dog is in heat. It lasts from 7 to 10 days, with 9 days being the average length.
During this time, the vulva swells. You may notice personality changes as well. Some dogs act the opposite of their normal behavior, while some are only a little different. It’s common for her to be clingy or standoffish during this time.
You may notice appetite changes as well. Some dogs eat very little, while others seem famished. Bleeding will also begin in this stage.
When a dog attempts to investigate her, she will sit down or put her tail between her legs. This is her way of saying she’s not ready to breed yet.
The next stage is estrus. This is when the female is actually fertile. You’ll notice flirtatious behavior with male dogs. She may wave her tail as a way of “flagging” potential mates. This is actually a scent cue instead of a visual one. With her tail held high, the male can smell that she is ready to breed. Bleeding still occurs, but it is lighter. The vulva softens to allow penetration.
Diestrus is the next stage of the heat cycle. Vulva swelling gradually subsides and hormone levels begin to normalize. Bleeding will once again become bright red before stopping. If she is pregnant, diestrus remains until birth.
If she wasn’t bred, anestrus occurs. The heat cycle is over. It will be 5-11 months before a new cycle occurs.
Hormonal changes are responsible for many symptoms of heat, including behavioral changes and potential nausea.
During proestrus, the female’s estrogen levels rise much higher than normal. Males will be attracted to her hormones and pheromones, but she isn’t ready to mate.
During the estrus cycle, estrogen drops and progesterone rises. The female is receptive to males during this time.
During diestrus, estrogen levels remain low. Progesterone reaches peak levels at 3-4 weeks after diestrus begins, and then returns to baseline at the end of the diestrus cycle.
Nausea and vomiting are common problems when a female is in heat. High hormone levels can cause gastrointestinal issues themselves. When the hormone levels begin to fall, they are processed in the liver and then sent to the gut. The gut expels them in waste. However, this can also cause stomach upset.
Pyometra usually occurs 3 to 5 weeks after the heat cycle. It’s an infection of the female’s reproductive organs. Signs include vomitting, abdominal swelling, lethargy, and fever.
It’s a life threatening condition that often requires emergency spay surgery. If your dog is vomiting several weeks after her heat cycle, take her to the vet for a check-up.
A dog’s heat cycle has the potential to end with pregnancy if a male is allowed to breed her. If your dog is pregnant, she may experience morning sickness. This usually occurs during the 3rd or 4th week of pregnancy and lasts a few days to a few weeks.
She may also be a bit tired or lethargic. Appetite changes can occur, with a period of less appetite followed by increased appetite as the puppies begin to grow inside her.
#2: Disorientation
Disorientation in a dog is one of the easier signs of overheating to spot. If you notice any of these things happening to your pup, it’s time to step in and do something:
Disorientation can become more severe over time and have serious health consequences. No matter how mild you think the condition is, you should treat your pup before moving on with your day.
When to Expect It and How Often Dogs Go Into Heat
If you got your furry companion as a puppy, youâre probably wondering when she will go into heat for the first time. Usually, this occurs between 6 and 24 months of agpuse, unless you get her spayed first. If you have a small breed, it can happen earlier. Larger dog breeds can take a little longer than 24 months. Your dog will typically go into heat at least twice per year.

Here, our Memphis vets explain the causes, symptoms and treatments for dog heat stroke, along with preventive measures you can take to ensure your pets safety.
Unlike humans who sweat, dogs eliminate heat from their bodies by panting. When panting isn’t enough, a dog’s body temperature rises, and they can experience heat stroke, which can become fatal if not treated immediately.
