as far as ideas.. Well, Do all you can to make him comfortable, make him feel as loved as ever before, start introducing some more raw treats for him; goat heads! Go for super casual walks in some woods somewhere..
Enjoy the time you have left
Do not go where the path may lead.. Make your own path and leave a trail.
~Ralph Waldo Emerson~
Those that matter dont care, and those that care dont matter..!!
You're not beaten when you lose, you're beaten when you quit..
