Blood tests? A few months ago one of our dogs had to be put to sleep as she had extensive liver damage that couldn't be treated. The thing is though, she was taking medication for epilepsy and had regular blood tests to see if the tablets were causing any liver damage, but they always came back with good results. I can't understand how this damage was missed by the tests, they even did a test the day she went in with a swollen belly and that came back OK too. I can't understand why the tests didn't identify the liver damage. They wouldn't have changed the outcome, but we could have made a decision to put her to sleep BEFORE she suffered so much. If this test is so inneffective it surely shouldn't be used. Has anyone else experienced this kind of thing?
