Short answer, not really.

A dog’s period is different than a human’s. See, a human’s period cramps happen because of the contraction of the uterus walls to shed its lining. Dogs, however, don’t shed their uterus lining – it’s the opposite – they try to absorb it. It does cause some discharge of blood, but it doesn’t involve contractions like humans’. It is presumed that they have some contraction of the uterine walls too, but not the same cramps as ours because, again, their reproductive systems work differently.

That said, dogs can be uncomfortable during their estrus cycle. If your dog is whining, it may be just to get your attention, or they do it as a mating call.

If you suspect that she’s in pain, contact your vet.
