Do female dogs have periods blood? When a female dog is in heat (called estrus), she has a bloody discharge from her vulva—similar to a human period or menstruation. But that’s where the similarities end. While humans experience a menstrual cycle every 28 days on average, dogs’ estrous cycle is six months or more.
How often do female dogs get their period? Most dogs come into heat twice per year, or about every six months, although the interval can vary between breeds and from dog to dog. Small breed dogs may cycle three times per year, while giant breed dogs may only cycle once every 12 months.
How long does a female dog bleed for? You may also observe that her vulva is large, red, or swollen with some bleeding or blood-tinted discharge. Your dog will only bleed for around half of the total cycle, usually 7 to 10 days. Generally, bigger dogs bleed more than smaller dogs, but it varies between dogs. Some dogs bleed very little.
What do you do when your dog has her period?
- Watch her closely. When a dog is in heat, her only thought is to breed, and she will often do whatever it takes to find a mate.
- Keep male dogs away.
- Consult your vet in emergencies.
- Close the windows.
- Take caution with walks.
