Sexual behaviour in dogs


BITCHES are more affectionate and easier to control than the male dog. They are about thirty per cent smaller and whatever their breed, tend to be more gentle with children. The bitch will come into season about every six months and this will last for around three weeks. The female is receptive to mating and extremely attractive to dogs that will instinctively try to mate.

A clear sign that a bitch is coming into ‘season’ is that she will produce a discharge; initially a bloodstain, that will be deposited wherever she sits. She will spend a great deal of time licking her vagina.



Be assured that your home will attract local male dogs that will camp outside for about three weeks. Expect howling throughout the night.

The female will attempt to escape at the first possible opportunity so it is wise to keep all doors closed, especially when greeting your guests. I have known bitches that have chewed their way through doors during the night to escape to get to the male dogs.

Do not underestimate the great heights that male dogs can climb to reach a bitch on heat. During this period it is well known that the male dog can be extremely aggressive.

If you are not going to breed from your bitch it is best to consider having her neutered a few months before her first season. The female will live longer and the likelihood of mammary tumours is negligible. She will certainly not put on weight.

The male

Male dogs, whatever their breed, tend to be more dominant than the female. The adult male has an instinctive urge to escape and wander free from home for periods ranging from an hour to several days or weeks.

Often a clear sign of a dominant male although house trained, will show when he starts to lift his leg in the house and urinate on walls and furniture. He does this to scent-mark his territory and to affirm his dominant status. This type of dog should be castrated.

Owners of dominant dogs should spend time re-enforcing their own dominance and insisting on absolute obedience. This can be achieved through a training club.

Dogs that are confined and not allowed to roam can develop sexual frustration and will mount the human leg and even mount children who crawl on the floor.

The best way to deal with this is to discuss the problem in an honest way with the vet who might consider either using a female hormone to try to counteract the condition or to castrate the dog.

I personally recommend castration for all dogs that are not to be used for breeding. A castrated dog is happy and is free from worry and frustration. He will be more pleasant to have around, less likely to fight other males and more submissive to the wishes of the human pack leader.

The best time to castrate a male dog is around five to six months before he starts to lift his leg. Your vet will advise when your dog is suitable for this minor operation. Within twenty-four hours your dog will have fully recovered from the operation.
