Bella is nearly 14 months old and started her first season almost 3 weeks ago. She had about 2 weeks of watery bleeding which started to tail off so we thought it was coming to an end but she now has a discharge with is thicker, darker (practically brown - looks a bit like melted chocolate) and it smells.
She was feeling sorry for herself in the beginning but is her normal self now.
Do I need to worry about this? (I am!) and should I ring the vet?
