Dog Pregnancy: What You Need To Know
Human pregnancy and dog pregnancy are quite different. Here is everything you need to know about signs, cycles, and how to care for your expecting dog.
Your pup’s reproductive cycle, otherwise known as “canine estrous”, has 4 stages; proestrus, estrus, diestrus, and anestrus. Here are some descriptions of each stage and what to look for with your pet:
Most people know this stage as being in heat or having her period. Typically lasting for about 9 days, estrogen levels rise and the female bleeds. She may seem unreceptive to male advances during this part of her cycle.
Otherwise known as ovulation, this is when fertility occurs. This also lasts for about 9 days normally. Not as common but it is possible to last from 4 to 24 days. Blood is decreased, progesterone levels increase while estrogen lowers.
Levels of estrogen are low and after hitting its peak 3 to 4 weeks after beginning diestrus, progesterone drops to its normal amount. This in-between stage lasts for about 2 months.
This is the final step and can go on for about 4 months depending on the breed. During this phase, her body prepares to renew the cycle again to get ready for the next possible pregnancy. This is her normal state.
If you are choosing to breed your dog, using this cycle information is key to success. While your dog is in heat, it is especially important to look at physical changes to be able to determine which cycle she may be at.
