Buffalo Bills head coach Rex Ryan was challenged to eat a dog biscuit to benefit the SPCA, a foundation dedicated to helping rescue animals. On Thursday, Ryan took up the challenge and ate the biscuit.

Not only did he eat one biscuit, but he found it so delicious, that he decided to have another. Classic Rex Ryan.

After eating his biscuits, Ryan challenged Sydney Pegula, team owner Terry Pegula's dog, to match his incredible accomplishment. Sydney dominated the challenge, of course, as did Terry, and proceeded to challenge defensive tackle Marcell Dareus next.

Maybe it'll help Dareus get the long-term extension he so badly desires. If the owner eats a dog biscuit, the player should do it too.
