My 9-month-old dog hasn't had heat. How to prevent pregnancy?

Injectable contraception is not without its risks in dogs. It would likely have been safer to isolate her from male dogs until her heat passed in a few weeks. It is good, however, that you plan on having her spayed,

This can be a difficult situation! Since Snowbell mated (I assume while she was in heat), there is certainly a chance that she may have become pregnant. At this point, your options are to either have her spayed very soon to terminate any possible pregnancy and prevent the occurrence of future pregnancies, or wait and allow her to deliver any pups. In this situation, it sounds as though spaying her would be for the best, but I realize that this is a personal decision. I hope that all goes well for Snowbell!

If she is a healthy dog, she should be fine. You can have her examined by your veterinarian. A vaginal swab can be examined in the clinic for the presence of sperm. There is a canine equivalent of the "morning after" pill for accidental matings. Your vet can dispense a 5 day course of a hormone pill to prevent pregnancy.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concerns. In regards to spaying, these procedures are not only done to prevent them from having puppies but also for prevention of conditions that would potentially put their life at risk. With females, the risk of mammary cancer and uterine cancer greatly increases. Also, females can develop a potentially life threatening condition known as pyometra which usually needs to be addressed with emergency surgery. In male dogs, prostate and testicular problems are greatly reduced with neutering. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

There aren't emergency contraceptives like the Plan B in humans but there are medications pets can take to end pregnancy. Not all vets carry them however. Start with a call to your veterinarian and go from there. The best thing you can do is have one or both dog altered to prevent any future pregnancies. There are both health and behavioral benefits: https://www.petcoach.co/article/benefits-of-neutering-castrating-male-dogs-puppies/ https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/ I hope this helps and best of luck.

If you don’t plan to breed her in the future then I would recommend spaying her as soon as possible. There are medications that can be given to abort the feti, but this can be very hard on the mama dog, and it is not 100% reliable. This is usually given under hospitalization observation. Best of luck and thank you for using Pet Coach.

If it is early pregnancy, she can be spayed. Some vets may also carry medication to abort the pregnancy. Having a litter prior to physical maturity can permanently stunt the growth. He may also see issues with the bitch being too immature to care for the puppies. If he decides to move forward with this litter, here is a link which may help: https://www.petcoach.co/article/pregnancy-diagnosis-caring-for-the-pregnant-dog/ I hope this helps.
