My 3 yr.old 4 lb. yorkie has always snorted like a pig.. Several months ago she was given kennell cough vaccine nasally and ever since has been sneezing. When it became severe the vet put her on an antihistimine. No change. Several weeks later she was put on Clindamycin 5 days later she was put under so a more through exam could be done.. Slightly enlarged toncils and teeth scraped were the results. Now that the meds have been completed with little to know improvement I'm wondering about the next step. Prednisone was suggested but I have rejected it becouse of previous bad experience and the bad side effects. Can anyone offer any offer any advise? What about natural meds?
