I’ve got a 14 year old Lab. He’s been a great dog and had a good run - arguably had a better life and more fun than 99% of dogs do, between hunting, camping, and kids. In the last year he has become deaf as a door nail, mildly incontinent, and his hips are failing. His back legs slide apart on our floors and he has trouble doing much. You can see in his eyes that he is still the same dog inside, but his body is slowly failing. We give him anti-inflammatory drugs to keep him mobile and minimize discomfort, but sooner or later that won’t do the trick any more and I’m not one to dump a bunch of money into a dog just to eek out another 6 months of poor existence. I’ve seen several dogs at the very end of their lives, and he isn’t there yet, but I’m wondering what criteria people use to determine that it’s time to put their dog down. It will be tough, but I don’t want him to suffer either.
