I don't know what it is about this pup but she constantly has me on my toes. She has now began eating again, but now her stools are mucusy looking. When I took her to the vet she had a cold which is being treated and she is coughing up alot of phlem and then swallowing it back down, would this cause the mucus? Should I be taking her to the vet again? I think if the mucus still shows tomorrow I will take her in.
