The usual age for a dog to have her first heat cycle is about six months of age, although in smaller breeds it may begin as early as four months of age. The first heat cycle in certain big breeds may not appear until they are 18–24 months old.

Young female canines should not be bred during their first and second cycles since their eggs are immature and they have not yet achieved complete development. Determine the right time to start breeding by talking to your vet.

Dogs' heat cycles last an average of two to four weeks. Some female canines are only receptive to males later in their cycles, while others are open all the way through. Different canines may have cycles of varying lengths. When her vulva shrinks back to its usual size and she stops bleeding and producing discharge, the menstrual cycle is done.
