Just got back from vets where Dragan had his bloods done. results show inflammation of the liver, elevated kidney readings and his heart murmur has worsened. Vet thinks it might be thyroid linked so has sent off to lab for thyroid test (will get result in about a week). Obviously if it is the thyroid then it can be medicated. If not then he is putting him on Fortekor (which my old dog was on for years) which hopefully will help. Poor old fella already has chronic pancreatitis and arthritis but is happy enough at the moment, eating, pottering, playing with Da Bird and giving lots of purry headbutts. Fingers crossed. Thanks
