Sorry for your loss. I'm still getting over losing my best friend, Keisha, less than a month ago. She was a rotti-shepard cross and smart as a whip. She was almost 15, but got bone cancer.
Geez that's terrible Growrock, my thoughts are with you. Almost lost one of mine exactly a year ago and to say I was devastated would be an under statement. Bringing tears to my eyes just thinking about it.
Your Renegade friend would want you to get really pain free by imbibing some marijuana. Of that I am pretty sure. I will eat some as if it was a weed in my garden and think of your friend.
