My darling lab is nearly 13. His arthritis has been managed for the last year or so, but this week he has suddenly deteriorated. He's now on 3 different painkillers and antibiotics (because he has chewed a 10cm wound on back leg, the vet thinks because of pain). Walks are now out of the question.
He basically needs watching 24/7 so he doesn't make the wound worse. He is eating intermittently, but not with his usual enthusiasm.... and then he has moments of seeming really happy, wagging his tail, enjoying a cuddle, gobbling down his dinner.
How will I know when I need to make the decision? It's so hard when he has these moments of seeming to enjoy life. Am I doing this for me or him?
