I'm not really an expert on this but Zach had KC for about 3 weeks after we got him but six weeks seems like a long time. Did the vet xray him or test him for CT. Yorkies are prone to them. My dog still coughs when he gets excited or drinks to fast and every once in awhile my shorkie coughs. Is there any other vet you can get a second opinion from? Also my vet says if my home has very dry air, which it does that can make them cough also. He told to get a humidifier. Also did you contact your breeder about this? |
