Terrible day today. My 15 year old dog has been off her food for a few days but was eating if we hand fed her. Just thought she was being fussy in her old age but this morning I went to give her a piece of cold meat and she wouldn't eat it. Later on in the morning she wet the floor even though she was able go outside. I knew immediately something was wrong as she never ever had accidents apart from when she was a puppy. Took her to the vet and was left literally reeling when she told me she had a massive tumour in her stomach pressing on most of her organs. There was nothing they could do for her. As she couldn't eat because of the tumour I made the decision to have her put to sleep rather than having her starve to death. My young son is devastated and thinks that I killed her but of course he doesn't understand. I know I did the right thing but even so, it hurts like hell.
