How long are dogs in session for?

Each heat cycle usually lasts for 2 to 4 weeks. During this time, your dog will likely bleed for around 7 to 10 days. Some dogs bleed heavily, while others bleed very little. Some pups will have longer cycles, and some shorter, but they should be regular. How long will my dog be in heat for is answered by the fact that each heat cycle usually lasts for 2 to 4 weeks. Once they’ve begun, their heat seasons should occur every six to seven months - roughly twice a year. Gaps between cycles generally become longer as dogs get older, but they can still become pregnant.

Each heat cycle lasts around 18 days, for generally anywhere from 2 to 3 weeks. The canine estrus cycle has four stages: Proestrus: The beginning of heat lasts between 7 and 10 days. Estrus: This is the mating period of the estrus cycle, it lasts 5 to 10 days. Diestrus: This period lasts anywhere from 10 to 140 days. Your dog will only bleed for around half of the total cycle, usually 7 to 10 days. Female dogs who have not been spayed go into heat twice a year, around every 6 months. The frequency depends on your dog, but her estrus cycles should be consistent. As your dog gets older, the frequency of her seasons may slow down, however, she will be going into heat for her whole life. Generally, bigger dogs bleed more than smaller dogs, but it varies between dogs. Some dogs bleed very little.
