She is bleeding because she is on her period. That means, she is at the age where she can be breed-ed and have pups.
I dont think so, take the dog to to a vet because that shouldn't happen.
Yes. Females do bleed when they are in heat. I would suggest keeping them in a linoleumed or tiled area to make cleaning up after your pet easier. You can also purchase "doggy diapers" for this specific purpose.
A big nappy.
No, they get pregnant about 3or4 days into the bleed
Well they bleed but only for about a week. They are still in heat though they are not bleeding
She is having her period!! Let her be.
It shouldn't. Take the dog to the vet.
Uhh... yeah I would take your dog to the vet...
It will stop bleeding after a while or it will not bleed at all
No, when a female is spayed all of her reproductive organs are removed. She can no longer come into heat and bleed.
The one mailing the other is more dominate
There are too many reasons that your dog could be bleeding. How long after the surgery was it? The best thing is to take your dog back to the vet. Only the vet can tell you what is wrong.
