Hey everyone! Unfortunately Tanks cough has come back, I've attached a link so you all can hear his cough, let me know what you think! He was originally diagnosed with Kennel Cough, and he was on meds for a few months, and then in doggy hospital on nebulizer for 4 days, when he came home he was not coughing, but had diarrhea from all the meds, thankfully diarrhea cleared up but now the cough is back

I have seen 3 different vets who all said it was kennel cough, but now my main vet would like to send me to a speacialist which I agree, and she's thinking it's due to his trachea. I know these little guys are prone to trachea collapse and other problems but I'm wondering why if it's his trachea, why did his cough disappear after nebulizer and he was cough free for a couple weeks before it came back...Anyway the only specialist is over an hour away from me and is booked for 2wks, so I'm hoping you all can give me some opinions on his cough, kennel cough vs. trachea etc...Thanks in advance!!
