The Reproductive Cycle in Dogs

In order to answer the question, "how long are pets pregnant," you initial requirement to understand the pet reproductive cycle. Undamaged female pet dogs enter into warmth about every 6 months, although this can vary depending upon the canine as well as the breed. The warm cycle lasts 18-to-21 days and is gotten into four distinct phases. Dog breeders use these stages to establish the best time to breed their canines.
