Planning to breed your pup or are you currently taking care of a pregnant pup? If so, there are some basics you should know about canine pregnancy. Contact your vet to talk about canine pregnancy and if you have a pregnant pup schedule a checkup for her. Your vet can verify if your dog is pregnant and should be able to give you a general idea of how far along your dog is. Most dogs have a pregnancy or gestation period that runs between 58 and 67 days. The average gestation or most common is 63 days. The days can change, however, depending on the dog’s breed and size as well as the number of puppies she’s carrying. Small litters have a longer pregnancy whereas larger litters may come sooner.
