I once read that some labs have an extra “hunger” gene adding to their food driven nature. While I am not sure if this is true physically, it certainly is in practice. Our Mr. Fili has swallowed socks, gloves, face clothes, make-up sponges and anything else he can get in his mouth. On the positive side, our house is never cluttered for fear of objects becoming a second dinner.
