Dog like this

Our Hero was travelling through the mountains on his quest for the Holy Grail, when a fierce storm blew up and his steed caught some horsey sickness. He hied to a monastary, and asked the abbot for a replacement, citing their loyalty to God. It was the winter season, and nightfall was approaching as they looked through the stables. All of the other horses were sneezing a coughing also, until they came to a stable, where a large shaggy dog story(oops) resided. The knight asked for him, to which the abbot replied, "Oh, no, it is still stormy and getting dark.

"I wouldn't send a knight out on a dog like this."
