Question about coughing

I have a Yorkie that neighbors found in street and gave to me. She was coughing and it got worse, took her to vet, xray showed collapsing trachea. She gave me prescription for two different syrups, hasn’t helped, saw Pawhealers online, ordered some herbs for phlem, doesn’t work, ordered herbs for slight heart murmur, doesn’t help, ordered NHV Resp-Aid and using for 3 days, hasn’t helped. Her coughing is getting longer in period of time. What do you do for your little dogs there? In between coughing spells, she runs around the house,barks at any noise, eats holistic food and stool is normal. What else can I do?
Thank you. I contribute every month.

 

Answer from Dr. Gaylord Brown:
Dog’s with collapsing trachea need to be kept at a good body weight. If they are allowed to get overweight they have a great deal more coughing. No treatment will cure the problem. We use a combination of aminophylline and torbutrol to control the symptoms.
