my coydog was sadie she is on my profile here. she was a sheltie mix. she had gotten better before she died. She had gotten better then the morning she got sick again she died on the way to the vet. Looking back at her symptoms and treatments and her responses to them she appears to maybe of had liver disease? I know shelties are prone to endocrine system disorders but am unsure about coydogs and can find very little informaiton about them. If anybody has any information on coydogs or health issues please let me know. My husband keeps telling me I did all I could, she was getting better, and to quite beating myself up over it. but that is so hard all i can think is she died so i didnt do enough!! even if it seems there was nothing else i could do. I miss her soo bad and will never find another dog anything like her if i searched the world!!
