Your dog can have an infection in the uterus called Pyrometra when she undergoes her heat cycle. She has a chance of getting pregnant a few weeks after beginning in the estrus phase of the reproductive cells. 

The white blood cells which usually protect the uterus from infection are absent in this stage. The cervix is also open so that the sperms can enter into the body of your female reproductive tract. So the bacteria present in the vagina make their way into the uterus, causing a uterine infection called Pyrometra.

The bacteria survive and grow in the uterus of your dog if the uterine wall is thick in your dog because of cystic endometrial hyperplasia.

The most common symptoms of Pyrometra are as follows

  • Vomiting
