A female dog's estrus cycle is the period during which she is able to become pregnant. These generally occur every six months, although there is some variation among breeds and individual dogs. Smaller dogs generally have less time between cycles, while big dogs have more. During each cycle, a dog is in heat for two to three weeks.

    Why do dogs get stuck after they mate?

    A:

    When dogs mate, the bulbus glandis of the male dog's penis swells inside the female dog's vagina, and this is a normal part of dog breeding. The act of the dogs getting stuck together is called a tie. The sperm is released during the beginning of the tie and prostatic fluid is released afterwards.
