Is my dog pregnant? She's gaining weight and was with an intact male.

Updated on September 23, 2025

Pet's info: Dog | Labrador Retriever | Female | unspayed | 2 years and 1 month old | 65 lbs

This is Robin, she is a 2-year-old black lab. We think she might be pregnant. We do have a boy black lab, that is not fixed that could have mated with her but we are not sure. We have been told this could be a false pregnancy, but she keeps gaining weight so, we think she actually is pregnant. Any advice?

Considering you also have an intact male in the house, it is very likely that Robin is pregnant. You should take her to your vet for an x-ray r ultrasound to determine how many puppies she will have so you can properly monitor her when she is giving birth. A dog's pregnancy lasts between 58 and 68 days (63-65 days on average) so when you think back when she stopped bleeding during her last heat, you can pretty much figure out when she will have her babies.
