I've been doing some more research and this isn't even approved by the FDA for humans... which makes me nervous to administer to a dog. It was approved, but due to side effects, it is no longer available. Veterinarians, however, can still prescribed it.
Do you think your dog is old enough to handle a pregnancy? If so, I would go through with the pregnancy. It's not worth it to risk the shot not working and having deformed puppies and a mommy dog now at risk for developing side effects such as cancer.
Besides, I hear yorkie-chis are pretty darn cute! |
