Yoday has been coughing for around 5 weeks. He started at 9 weeks and we got him at 8 weeks. He is on his 4th antiobiotic and has taken a steriod. Also, he is taking something to open his bronchial tubes. The vet did a xray and can not find anything wrong. Yoda's trachea was very sensitive to the vet's rub. The vet also said that there is nothing else he can do if the last medicine does not get rid of the cough!!! After 2 days, he still is coughing. I am so frustrated!!! Other than the cough he is very healthy!
