Well Gunnys interdigital cysts (deep pyoderma) are back after a month of treatment with clindimycin they are so painful to him it just breaks my heart. Last month when we were at the vets he said the last thing we can try is atopica he said they had good results with it but it will cost 300.00 a month for awhile and cut it back after awhile I gotta do it cuz I can"t let him suffer and he"s worth it. He goes to the doctor Thursday.
