Q: Why does my dog curl up in a ball to sleep? Surely he’d be more comfortable if he spread out?

A: Some dogs prefer to sleep curled up, and whilst we may anticipate that they would be more comfortable if they stretched out, it seems that this curled-up sleeping posture is inherited from their ancestors.

Dogs in the wild will dig a nest to sleep in and curl up in it – especially if it is chilly. This will help keep them warm and also keep their vital organs hidden away from predators. A dog will only stretch out if he feels safe and secure or is very hot!

Because of the preferred curled-up posture, a round bed might make your dog feel even more comfortable. Alternatively, he might just like a blanket to dig in and make his own nest!
