First you have to have the vet do the tests to determine it is indeed collapsed trachea. Coughing could also be caused by kennel cough. a respiratory infection, reverse sneezing or heart problems. If she does indeed have CT the only thing you can do is protect the trachea AND hope it doesnt worsen. I have heard there is a stint surgery they can do but its not very successful buut you can talk this over with your vet after you have a firm diagnosis |
