Dogs are in heat for about twenty one days. There are three stages in a female dogs' heat cycle.
Most female dogs have two estrous cycles yearly. I keep hearing that they can go into heat as late as 14 mo,
Six months on average.
i have a female 2 year old Chihuahua . i have found that it has been nearly two weeks for her cycles to run their course. but thankfully it is only every 6 months and is like clockwork.
The female dogs in Nintendogs is pregnant for 24 hours. You need to have the male and female dogs in the same room wearing the lucky collar in order for the female to get pregnant.
Dogs do not have menstrual cycles like humans do. Female dogs go into heat, which is a period of fertility, but it does not involve cramping. If you notice your female dog in pain or discomfort, it's best to consult with a veterinarian to determine the cause.
