Keila came into her first heat about 2 weeks ago, She stopped bleeding 3 or 4 days ago. and I just noticed that she is spotting again. She is still swollen, but not as much as she was at the beginning. Is that normal or should I be worried. She is my first female dog so I dont know what to expect as far as her heat cycle goes. Im freaking out a little and not sure if I should be. Help!
