QuestionI have a female Jack Russell Terrier and she just came into Heat. How long will this last????
Thank You,
Mark
AnswerThe first part of her heat, called Proestrus, lasts 10-14 days. That's when she will swell and bleed. Ten she goes into Estrus, or standing heat. This is when she will breed to the male. This can last 5-10 days. After that, she goes into Metestrus for 2-3 weeks. Than is when she cleans out her uterus. The rest of the year, she is in Diestrus, or resting.
