Biggie got nasal spray for kennel cough a week ago, 2 days later he has what seemed like a cold (phalange and cough and green snot) called the vet told me to watch it for 48 hours incase it gets bad, it didn't, he's beginning to recover now, he is acting normal but he still has a clear runny nose, I'm going to wait it out, if he goes back to where he was 2 days ago, then it's time for the vet.
