Note that the new drug, Rimadyl, has been found in rare instances to produce a severe, but reversible form of liver disease. Check with your vet if your Scottie is on this medication for arthritis or other pain. Oxibendazole, an ingredient in Filaribits Plus is thought to have caused liver damage in several kennels of Scotties, when the product first came on the market years ago. The drug caused severe, but usually reversible liver disease in some dogs, although I heard that some Scotties did die. I remember hearing that the company came through and supplied regular Filaribits for the rest of the dog's life.
Anticonvulsants can cause changes in blood work and can occasionally cause true liver disease.
Prednisone and Cortisone, whether given to treat specific diseases or erroneously produced in excess can cause Cushing's Syndrome. I am always cautious when using steroids because of adverse side effects they can produce. Carole Owen related a story about a Scottie having bad liver counts after ingesting a chocolate bar. She had taken a visiting Scottie in for a teeth cleaning. During preliminary blood work, her vet discovered irregularities in the dog's blood count.
