My dog is coughing mostly at night when we are in bed. It is kind of a cough where it sounds like she is trying to get something up. During the day she is sneezing alot and seems to have a runny nose. I am not sure if it is a cold or what. Also she still has energy wants to play and drinks water but is being very picky about her food. She strictly wants table food. Anyway the coughing is a little concerning. Is it something I should worry about she is 5 months old.
