The Vet has her on Hydrocodeine syrup after trying everything in the book. They can control it but not cure it. I am up at 4 am listening to her hack. It sounds worse than before. I am taking her to the vets as soon as they open. The hydro is $75 a bottle and I don't think it works all that good. My question is , Has anyone else had a dog with similar problems? Wanna kill these ads? We can help!
