I know how you feel, and I hope your family get's better. I didn't have a dog, but an Iguana. he was like my child. Raised him from a couple inches long all the way up to 4 1/2 feet long. he rode everywhere with me in the Ironman. He loved it, even at 120 mph through the desert on highway 666 through the Indian nation(had to dump a gallon of ice water on him to cool him off), countless trips to Colorado, Arizona, and South Central to the hood when I used to be married.
So, I can only imagine how you and your family feels about this and what you all are going through.
