Female dogs usually go into heat twice a year, with the first cycle occurring on average between 6 and 12 months of age. It can occur earlier in small breeds or later in large breeds.

  • Q:

    Do spayed dogs menstruate?

    A:

    Dogs that undergo the spaying process usually stop menstruating, but there are cases where a dog appears to be in heat following surgery, which usually means that the surgery did not completely remove all necessary reproductive tissue. After tests to confirm that a female dog still has some reproductive tissue, a veterinarian can perform a secondary surgery to remove the remaining tissue.
