While in heat, your furry friend will usually bleed for 7 to 10 days which represents about half of the estrus cycle. Smaller dogs bleed little and if your dog is bigger you should expect her to bleed more.
Can A Dog Bleed Longer Than 10 Days?
Yes, if it is a big dog breed, they can bleed longer than 10 days but it shouldn’t exceed 12 days. For smaller dog breeds, it’s not ideal that they bleed longer than 10 days.
For most dogs, the normal range for them to bleed is approximately 7 to 10 days and this is usually midway between the proestrus and estrus stages.
Some bigger dog breeds will usually have heat lasting up to 24 days and will bleed more. The bleeding could take up to 12 days to stop. While the smaller dog breeds that have their heat lasting up to 2 to 3 weeks will bleed less for about 10 days.
In any case, if you have a bigger dog bleeding longer than 12 days, or a smaller dog bleeding longer than 10 days, you should visit your veterinarian.
Your veterinarian will help to determine if the prolonged bleeding is from the type of dog breed or if there is something wrong with her.
In canines, prolonged bleeding during the estrus cycle could be a sign of a blood-clotting disease, like von Willebrand disease.
Similarly, if your female canine bleeds for less than the normal days, you should also visit the veterinarian. Little bleeding than normal when in heat could be an indication of infertility or tumor in her reproductive organs.
How Long Does A Dog Stay In Heat?
It takes 2 to 3 weeks for dogs to stay in heat. And this is the normal range for most dogs.
However, considering some smaller and bigger dog breeds, the length of stay in heat is between 1½ weeks to 4 weeks.
How Do I Know When My Dog Is Most Fertile?
Your dog is most fertile just the moment before she stops bleeding, and this period marks the end of her estrus stage.
The period of most fertility varies in dogs. For most dogs, it occurs around Day 10 to 14 which is towards the end of the estrus stage. Again, this depends on the breed of dog, their age, and size.
You should consult with the veterinarian to ascertain when your dog is most fertile. There are two tests that your vet can perform. Your vet can perform either a vaginal cytological test or serum progesterone tests.
