@BartH - I know that feeling too well. Dealt with 2 cancers with my old yellow lab and toward the end it gets really heard to know when to let go. My vets advice was to watch for when he no longer enjoyed the things he always had - chasing a ball (even walking to get it) and food. Now, our Australian Shepard has lost 50% of the mobility in his rear legs and has a little paralysis in his larynx so his breathing is labored, but we are told this is common for the breed. We are worried about him but he still loves walks and belly rubs, and is always nearby so he appears to still be enjoying his "retirement". I don't look forward to the day the time comes for him and I hope your old man has more quality time left than you believe.
