Here's Why Your Dog Spins In Circles Before Lying Down

This bedtime ritual is thousands of years in the making.

That little pre-nap spin your dog does is a habit passed down from its wild ancestors.

The turning also let them check their surroundings and settle facing any potential threat.

Your dog has a memory-foam bed now, but the ancient instinct to make a perfect spot never left.
