Only female dogs go into heat.

Is your dog on any medication?

Neuter him

Dog Viagra? Dogs only react to a female in heat, they do not go into heat.

Medication? Anesthesia. To remove his testicles.

I really hope that you're not asking this because you want to breed, especially since you don't even know that male dogs don't go into heat.

I don't think he's the dumb one He's smart enough to know that having sex produces puppies, and there are more than enough backyard breeders out there already.

Get him fixed, don't breed, you don't know enough to do so.
