Life's realities

Everyone must learn the realities of life.. things are born, they live, and they die... but I'm NOT ready for this one.  Our dog Sasha, will by 13 sometime in May, we think.  She's gone from healthy robust to skin and bones.. seriously you can feel all the vertibrae in her back when you pet her. This is not good. We're waiting on blood work results. I really hope she just needs canned food and more love.. I can do that!!!
