I have a husky that's is 18yrs old, she has had siesures most of her life, and id mostly deaf and now is getting sores that won't heal. I too will be facing this decision soon. I picked her out of the litter the day after she was born. I figured if she stops eating and don't get up it is time. She is outside and loves it there, if we bring her into the house she just sits by the door and wants out. so I feel you pain about your pup.
