Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 1 year and 6 months old | 35 lbs
My dog has been waking up each morning and coughing and she repeatedly throws up white mucus. Yesterday it progressed and she threw up a dark brown substance. It is only in the morning. I would have already taken her to the vet, but she is eating, drinking, and going to the bathroom normally. Her demeanor also has not changed. She is still hyper and playful.
