About Dog Pregnancy and the Rabies Vaccine


My dog started her heat cycle last Tuesday. The amount of blood has decreased and turned lighter. Is this the second stage of the heat cycle or could she be pregnant? If she is pregnant, can she still get her rabies shot without hurting the puppies?

Hi Janey,

Yes, this sounds like the second, fertile stage of your dog's heat cycle. There is a significant risk of aborting the puppies when vaccinations are given to pregnant dogs, so I would recommend that you hold off on your dog's rabies shot until after she delivers, if in fact she is truly pregnant. If you witnessed any breedings, then I would operate on the basis that she could be pregnant. You might also want to call your veterinary clinic and get your vet's professional opinion whether it's safe to give a pregnant dog a rabies shot. You should be able to get a quick answer over the phone without having to make an appointment.

Thanks for your question, and I hope everything works out for the best.
