Is it true that well bred pure dogs will lay down on their stomach with hind legs stretched out behind them where as a mutt curl under?

That's a myth! There's no scientific evidence to support the idea that purebred dogs lay down differently than mixed-breed dogs.

Here's why this is a misconception:

* Individual preferences: Dogs, regardless of breed, have individual preferences for how they rest. Some might prefer to stretch out, others curl up, and some might even have unique sleeping positions.

* Comfort: A dog's preferred sleeping position is often dictated by comfort and temperature. They might stretch out on a warm day to cool down or curl up on a cold night for warmth.

* Breed-specific traits: While certain breeds might be more prone to certain sleeping positions due to their body structure or temperament, it's not a defining characteristic of purebreds vs. mixed-breed dogs.

It's important to remember that judging a dog based on its sleeping position or any other physical trait is not accurate or fair. Every dog is unique, and their personality and behavior are influenced by a wide range of factors, including genetics, environment, and individual experiences.
