My dear old boy was 20. An amazing age. He had been struggling for the past few weeks but was eating and drinking really well. But his sight and hearing were poor. He had diabetes and an awful cough that could've been fluid on his lung 
. We were taking it week by week and then day by day. I left it too late. He had his tea, got comfy by the fire and then he got up and wobbled all over. His mobility was gone and his little face was so distressed. So we rang the emergency vet and it was all over... so quick and ultimately peaceful.
It's sad to think he ate his tea and wanted to settle in for the night and now he's gone. The vet said he had a long life and was more than ready. I do know that. But it's sad 💙
