I know puppies usually go into adolescent age about 6 months and the first heat can happen anytime from 6-9 months. How does a female act when she is in heat? Are there any warning signs before she goes into her first heat?
Some days before the first drops of blood are seen the bitches vulva swells and u notice frequent urination....Another sign i see with my female is she becomes really friendly with everyone!(shes a shy dog on her reg days)
