I bought a Lab puppy in the beginning of November, her 1st vet appointment was on the 15 about a week after that she started to have a mild cough. At the randomest times though never when she is playing, running etc. Its always like when she's laying down, or at night when she's sleeping. She has never thrown anything up its like a hack almost you can say. Its probably Kennel Cough but it seems to be really mild she only does this about 2 or 3 times at the most a day. She's a very active and alert dog, she's been vaccinated 2 times for Bordatella. She has a vet appointment this Saturday, do you think I should take her sooner?:(
