Is it normal for a dog to bleed three weeks after giving birth to a litter of seven puppies?

it might just be her period!! dont panic x

Answer:It depends; you don't say whether the puppies survived.

If the pups died and the mother "dried up," she could possibly go into heat again.

If they survived and she's still nursing them, no, it isn't normal. Female dogs don't go into heat while they're lactating, so it can't be her "period" under those circumstances. You should contact a vet.
