Hi All!
Back from the vet! She said we can't rule out CT, but she doesn't think it is that serious of a concern at the moment. She suggested giving him a cough syrup and seeing how that goes for a few days. His cough HAS gotten better in the past two days so I'm hoping he has a little infection and it is clearing. My other dog hasn't been coughing so I think we can rule out KC.
Thanks for all your support and good thoughts!
