DOG FAQ - Is my Chihuahua a dog or a mole?

It is a characteristic of the Chihuahua to prefer to sleep under a cloth or blanket. They will even get under pillows in order to feel snug. If you are raising a puppy, be sure to provide them with a soft towel or blanket in their sleeping area so they can burrow underneath it.

So don't be surprised if your Chihuahua scrambles under your blankets at night, even though your house or apartment may not be particularly cold. This is known as the "moley-effect."
