The medication that you heard about is a drug called megestrol acetate which goes under the name of Ovaban or Megace and is used to delay the onset of estrus in dogs. The protocol recommends that the owner start the medication when the female first shows signs of coming into heat. It is a tablet that is given daily for the first 8 days. The signs of heat should stop within that week and your pet should remain out of heat for 4 to 6 months on the average. She should then resume her normal heat cycles unless you decide to repeat the medication. It is not generally recommended to continually use the drug to stop each cycle in lieu of having your pet spayed. You should always have your pet examined by your veterinarian before starting this program, because she will need to be free of any uterine infections. This medication cannot be used on dogs before or during their first heat cycle.

In bitches, estrus suppression, for no more than 24 months, can be accomplished by administration of mibolerone. To be effective, treatment must be started at least 30 days before estrus. If the bitch has already entered proestrus, megestrol acetate may be used to stop the cycle. Administration must start in the first 3 days of proestrus. To delay estrus, treatment with megestrol acetate is begun in late anestrus. After treatment, estrus is seen in 2–9 months, and fertility is not affected. The efficacy to stop estrus is between 90% and 95%. Clinical use of deslorelin for estrus suppression is under investigation. Extended-release implants of deslorelin can suppress estrus for >1 year in bitches without apparent adverse effects and with full return to fertility.

Megestrol acetate is a synthetic progestin: a hormone used to postpone estrus (heat cycle) and to relieve the effects of false pregnancy. It can also be used to treat benign prostatic hypertrophy in male dogs and to treat skin and behavior conditions in cats. This medication is given by mouth in the form of a tablet or liquid. Do not use this medication to induce a heat cycle or in dogs prior to their first heat cycle. Avoid mating dogs that have a heat cycle within 30 days of completing megestrol acetate therapy. Megestrol acetate should NOT BE USED in pets that are allergic to it, have uterine disease or uterine bleeding, have diabetes mellitus, have breast tumors, have blood clots, are pregnant. This medication should be USED WITH CAUTION in lactating pets, as this medication enters the milk and the effects are unknown, cats with known viral infections, dogs with abnormal cycles.

For some owners, spaying may not be immediately possible due to medical reasons or plans for future breeding. In these cases, hormonal contraceptives provide an alternative to prevent or delay heat cycles temporarily. These include long-acting injections such as Delvosteron or Proligesterone that suppress the release of eggs or prevent implantation by manipulating the dog’s hormonal environment. The treatment protocol often starts with an initial injection followed by repeat doses over several months to maintain suppression. However, these methods have drawbacks, including possible side effects like weight gain, increased risk of uterine infections, and negate many benefits of spaying including cancer risk reductions. Additionally, fertility may not return immediately once injections cease, particularly after prolonged use over a year. Spaying, a surgical procedure called an ovariohysterectomy, involves removal of the ovaries and uterus and is the most definitive way to prevent heat permanently.

There are two different methods you can use to prevent her heat cycles. Fortunately, there are a number of medications your vet can prescribe that will stop the heat cycle. The most common of these drugs are referred to as GnRH or Gonadotropin-Releasing Hormones and can be purchased as either an injection or a subcutaneous implant. Both of these options are available for most breeds of dogs and work with equal effectiveness for as long as you keep your dog on the medication. These medications are highly effective at stopping your dog from going into heat. Today there are a number of medications available that are essentially the canine equivalent of birth control pills. The big difference is that they completely stop the heat cycle in a dog, whereas in humans, the birth control pill stops pregnancy by preventing ovulation or the release of eggs.

There are two methods to prevent estrus, or heat, in a female dog.
1. Surgery - ovariohysterectomy (spay): Recommended.
Ovariohysterectomy, or a spay surgery, involves the surgical removal of the entire female reproductive tract, including the uterus and both ovaries.
2. Medical management using hormonal drugs: Not typically recommended, due to risks.
Provides medical control of estrus: There are currently no approved medications to control the heat cycle in dogs in the United States or Canada.
In European Union countries, some medications are used to prevent pregnancy and regulate estrus.
Some of these drugs have a high incidence of serious, even life-threatening side effects.

If your dog is in heat, she’ll require a bit of extra supervision and care.
If you’re worried about your dog bleeding around the house, you can create a limited space for her to roam in.
This usually means restricting her to easy-to-clean areas without carpeted floors or upholstered furniture.
Creating a nest for your dog to nap in with towels to catch the blood will help prevent any accidents from occurring.
Doggie diapers can also help control bleeding accidents.
If you want to avoid pregnancy, you can have your dog surgically sterilized before her first season.
Since the timing of the first heat cycle varies, these procedures are recommended before she is 6-months old.
Not only will she be attracting male dogs, but she’ll be attracted back!
To avoid pregnancy, you’ll probably want to keep her away from other non-neutered dogs.
This is true even in your own household.

If you're not planning to breed your dog, the best way to prevent her from going into heat is to spay her. Non-surgical options If your dog isn't able to be spayed due to a medical condition or you'd like to breed her at a later date, megestrol acetate can delay or prevent heat cycles. Megestrol acetate is available in pill and liquid form. One study found that megestrol acetate had a 92% success rate in delaying the heat cycles of dogs in the early proestrus phase and a 98% success rate in dogs in the anestrus phase. Other medications that prevent and permanently suppress heat cycles include mibolerone and proligestone, but these aren't available in the US. Dogs who haven't yet experienced their first heat cycle shouldn't take megestrol acetate. Female dogs shouldn't be bred within 30 days of completing their megestrol acetate regimen. Do not use this medication for more than 2 heat cycles.
