The average dog will stay in heat for a period of 21 days. Female dogs have a cyclic sexuality that does not correspond to the season like most animals. It does not matter if it is winter or spring. This has no effect on the cycle of the female dog. Male dogs do not have cycles and are ready for intimacy with a female at any given time. In this way they are similar to the human male. Female dogs’ cycle last for around six months so they are in heat an average of two times per year.
Thee Distinct Stages of the Heat Cycle. These stages include:
This is the first stage of heat for a dog. During this stage there may be some bleeding that comes from the vulva of the female dog. The bleeding may be heavy or it can be light. If the bleeding is heavy you may need to purchase panties or disposable diapers they were designed for dogs. These products can be found in many pet stores as well as online.
“Washable Dog Wraps”, “Machine-washable, easy-to-use diaper wraps for dogs. Useful for untrained puppies, females in heat, and dogs that suffer from excitement urination or incontinence…”
This will help reduce the mess around the home. The vulva may swell up and the dog may have to urine more frequently. This stage of the cycle will last around 10 days. During this time there may be male dogs hanging around the home. They may want to breed even if the female ignores them. The dogs may even howl to get her attention during the day and the night.
The duration of this cycle will vary based on the size of the dog. Larger dogs such as Great Danes develop at a slower pace than small dogs such as the Chihuahuas.
This is the second stage of the heat cycle. This stage begins on the tenth day since the dog started bleeding. The blood may change from a bright red color to clear discharge. The female dog will allow any male dog to mate with her. This can last for a period of four to seven days. The dog can become pregnant at this time and can even have a mixed litter.
If you are not ready to take care of a pregnant female and puppies than you should keep the dog inside the home during this time. Your dog may try anything to get out of the house and meet up with the males. If you want to allow your dog to breed look for the way she moves. If she stands and move her tail away when you go to scratch her she may be ready.
When a female dog reaches six months in age they may go into heat for the first time. Since the dog is not fully grown it is not a good idea to allow her to breed. If the dog gets pregnant at a young age she may have complications that can affect both her and her puppies.
This is the last stage of heat when the dog is ending this cycle of the heat. She will be giving off a heat scent that will attract male dogs. There will be male dogs all around that are desperate to get her attention. At this time she will once again not want to be bother with the males. She may even snap or growl at them if a male comes too close for her liking. This stage lasts for around 10 days. Once this time is over the dog will no longer be in heat. Within the next six to eight moths she will go into heat again and the process will start all over.
