First heat I just was wondering about a yorkies first heat. How long should you expect it to last, the bleeding part. When should you start to worry? My mom's yorkie got her first heat and it just seems long to me, Stormy got hers and it passed and her is still bleeding a bit. We are starting to worry a bit. A book my mom read says it can last up to 6 weeks, this is going over 6 weeks now. |
