How can I tell if my bitch is in heat

During a heat (or oestrus) a bitch becomes attractive to male dogs and, if mated, may become pregnant.

One of the first signs is interest from male dogs.

The vulva (genital area) at the back swells and there is a bloody discharge which later becomes clear.

Some bitches lick this away, so if your bitch is licking, investigate.

There is a risk of pregnancy throughout oestrus, therefore keep your dog on a lead.
