What are the symptoms of menstruation (heat or estrus) in female dogs? Apr 25, 2018

Hi Raymon,

Some of the signs of heat, or estrus, in a dog are:

– Swelling of the vulva

– Bleeding from the vulva

– Mounting behaviour (trying to jump up on other dogs or objects in a ‘humping’ position)

– Licking of her genital area

– Nervous, anxious or nesting behaviour

– Urinating more often

I’m not entirely sure what you’re asking, I speculate as to whether you may be worried that they were spayed but still exhibiting the behaviour of being intact or you’re breeding them and need to improve your success rate. I will provide further advice if you need it.

Thanks and good luck!
