Every six months for two weeks on average.
My dachuand was in heat for 2 weeks.
A dog's heat cycle is 3 weeks. It does not matter what breed or size of dog it is, they all have the same length for their heat, which is 3 weeks.
Usually heat cycles last for around two weeks. Every dog is different so it may be longer.
Depends on the dog. THere are three stages in heat. The each last 3 - 7 days, so that means it last 9 - 21 In fact heat lasts ages even for ever.
If the female dog has a normal heat cycle, it last 21 days.
The female dogs come in to season or heat twice a year. Each season last fiive to 10 days.
A dogs heat in a period may or may not last very long. It depends. About minimum 15 days. Maximum, about 25 to 30 days. It may even last a month
A dog will go into heat approximately 4 to 6 months after having puppies, based approximately 6 months after her last heat cycle. When she goes into heat again will depend on how often she goes into heat per year. Most dogs go into heat twice per year, or every 6 months.
Spotting varies with each dog but typically last three to five days. The heat can last up to three weeks.
I personally think that no dog should be left out in the heat for long periods of time....
Females go into heat every five to nine months. So five to nine months after her last heat she will go into heat. The litter should not affect her next heat cycle.
This varies dog-to-dog - average is every six months but it could be more or less often.
