Unsure

Question
I'm unsure that my pug is pregnant. She is only 8 months old and I'm unsure if its safe for her i know your not a vet but we need some help with this her nips are enlarged please help

Answer
The nipples do enlarge after a bitch's first season, but that doesn't necessarily mean that she is pregnant.

If your puppy had absolutely no access to a male dog, then she cannot be pregnant. If she did, or might have, then she needs to be examined by a veterinarian to determine if she is pregnant or not.

If you do have trouble watching and confining your bitch when she is in season, I suggest that you have her spayed to prevent unwanted pregnancies.
