Could it really be a collapsed trachea. Ya think?? He is fine other wise. He sleeps good, eats good. He never makes this noise unless he is running around with a toy in his mouth. He was just at the vet for his one year check up and he was fine. What other symptoms are there related to a collapsed trachea? I'm trying to figure this out. I don't want to over react and take him to the vet because he just grunts.
Thanks for the help.
