Dog is 8 years old and not acting himself at all today. He was fine last night - walk early morning but he refused his food and he's been just...really off and ill all day. He wants to be outside all the time, he's isolating himself from us and he even went right to the bottom of the garden where he never normally goes. He's got a low temperature (we went to the vets! I insisted) and he was vomiting earlier, but the meds the doctor gave him seem to have stopped now.
I'm scared he's isolating himself because he's ready to die or something. My parents are paying for the vet bills and I feel guilty enough that I can't chip in. He's the best dog in the world to me and I really cannot go on without him right now. He's not old for his breed.
