What should I do when my male dog is in heat?

When a male dog is in heat it often becomes excited and active, and shows mounting, random peeing, and other signs. As testosterone rises, it may also display mock-mating behavior, such as humping toys or the owner’s leg. Besides the hassle, long-term heat can harm the dog’s health.

So if you have no plan to breed him, it is best to have him neutered at a vet clinic. If you do not want neutering, increase his exercise during heat to burn off excess energy and ease his urges, or find him a mate to breed with.
