My lovely dog has liver failure. Function tests are awful and his spleen/gall bladder are covered in masses. His liver looks horrible on screen, all dark and abnormal.
He has been my constant shadow since we adopted him and he would be 14 in February.
I don't know what to do but the vet said the moment his quality of life reaches that point to bring him in - he ate his dinner today because I encouraged him by mixing it with pate.
He's still like a total puppy in his head 
Bounces up then realises his body doesn't do it.
I lost my favourite cat (his best friend) this week last year and I just cried for days - now he's going Im just bereft.
He's lying next to me now wondering why mummy gave him ham when he's had a healthy diet his whole life til the last couple of days.
I love him so much
