My Border Collie is producing milk does this mean she is pregnant?

Question

She does not look pregnant. She has not gained weight but I know that when she was in heat back in early July my mothers dog was mating with her.

Answer 1

Yes, and she's going to have puppies in the next couple of days.

Answer 2

Maybe ...

Could be a false pregnancy too.  Only way to know for sure would be to take her to the vet ... or if you wake up to puppies.

Answer 3

Yes

Answer 4

that is possible, or she has a false pregnancy?

A vet could examine her, and tell you, if this is real or "fake" pregnancy.
