Oh Marla,
I am so sorry for the loss of your precious Coco. It could happen to any of us who have larger furbabies. I know my Mozart (23lb mix) is constantly putting up with Abigail's snips and snaps. He's such a gentleman though, he won't discipline her. Perhaps he knows that one bite is all it would take to do real damage. I just feel so sorry for him; he's in his 13th year, and here is this li'l snippy thing in his face.
Please, grieve as you need; but, don't blame-grieve. Coco, like so many of our Yorkies, thought she was a Rottie.
RIP, sweet baby girl.
