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.
