Canine herpesvirus is an infectious disease that is a common cause of death in puppies less than three weeks old. Pseudorabies is an infectious disease that primarily affects swine, but can also cause a fatal disease in dogs with signs similar to rabies.
Progestin-only birth control pills, sometimes called âmini-pills,â have several effects in the body that help prevent pregnancy: 1  The mucus in the cervix thickens, making it difficult for sperm to enter the uterus and fertilize an egg. 2  They stop ovulation, but they do not do so consistently.
There is VERY little evidence that the hormones in the birth control pill will cause birth defects. The birth defect hype came from the drugs that were given to women who were ALREADY pregnant, to stop miscarriages. Don't stop taking the pill until a pregnancy is confirmed. It will not damage the zygote. Comment.
