The 19 year old (yep, 19!) dog in the picture below, named Schoep, lives in Wisconsin with his AWESOME owner, John. Schoep has really bad arthritis so every night his owner takes him into Lake Superior to soothe him, cradling the elderly dog in his arms as he rocks him to sleep. The water is therapeutic for the dog's aching bones.

My wife and I have three large dogs and I can absolutely see us doing this in the future if necessary. Gotta take care of your best friend! -Matt
