Injections are the most common method of contraception used by dogs. They have been around since ancient times and they still work well today. There are several types of injections available for dogs, but there is only one type that works best for all breeds: injectable progestin (also called “the female hormone”). Progestins act like estrogen in humans, so it’s not surprising that they’re effective at preventing ovulation in dogs. There are two main kinds of injectables: injectable progesterone and injectable levonorgestrel. These are the most commonly used options for dogs because they’re inexpensive, easy to administer, and effective. However, these methods aren’t always ideal because they don’t protect against sexually transmitted diseases (STDs) or other health problems that may arise from hormonal imbalances. Another option is to use a vaginal ring. A vaginal ring contains a small amount of hormones that prevent ovulation. However, the ring isn’t as effective as injectable progestin because it doesn’t contain any estrogen.
The last option is to use a copper IUD (intrauterine device). Copper IUDs are inserted into your uterus and block the release of eggs from your ovaries. This prevents fertilization of an egg by a man’s single celled gamete, which would result in pregnancy. These are very effective at preventing pregnancy, but they don’t protect against STDs or other health problems that may arise from hormonal imbalances.
They are more common in female dogs, but they aren’t used as often in canines as they are in human females due to their expense and difficulty of use. There is a wide selection of safe and affordable birth control for dogs. It might take a bit of experimenting before you find the one that’s right for you and your pet.
