How long does a dog and cat stay in heat?
Dogs will generally stay in heat 3 weeks, the first week “coming in heat” where there will be discharge and interest by the males. The second week is generally when mating will occur, by the third week, there is not much interest by the female for the male. Females will cycle approximately every 6 months. Cats are different; they may cycle every 10 days until they are spayed or become pregnant.
