Bob Schwartz can attest to the truth of that old saying about dogs being man's best friend.
Schwartz has spent every moment of the last two months with Jay, a golden Labrador retriever, by his side.
Intelligent and affectionate, Jay provides companionship for Schwartz, who lives alone. But as an assistance dog, he also helps Schwartz with dozens of tasks.
"I can just tell him, 'Pick this up for me, open the door for me, carry this for me, pull me so that I don't have to (push) the wheelchair,'" Schwartz said.
