Gagging Cough Anyone on here with a dog with a collapse trachea. What does the cough sound like. I just got a new puppy. 4 months old and he does this gagging cough like he is trying to get a hairball up and sometimes saliva will come up. I am panicking because I lost a maltese to a collapse trachea at 10 years old. I can't remember what the cough sounded like. Does the gagging sound like collapse trachea or allergies. He is very itchy to. Thanks |
