My girl was diagnosed with kennel cough on Thursday afternoon, at which point she was perscribed antibiotics. She hasn't coughed much since then, but has been very lethargic. I've also noticed one of her eye's has been watering like crazy. Could that be from the cough? I haven't called the vet yet about her eye. I thought one of you might have some advice. She is out first dog, so all of these things are new to us!
