Our vet did a trachea swab and sensitivity on three of ours because of a persistent cough. He found strep and pastuerella. Doxycyclene (tetracyclene) and baytril worked to clear it up the first time but it came back. They worked the second time too, but it came back again. Albon appeared to work the third time. Then we used a nebulizer with amikacin and dexamethasone. It still comes back in some. It might be worth a trachea swab and sensitivity test to find out what is going on in these types of situations. tle www.ferretfamilyservices.org [Posted in FML 5651]
