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

While certain body postures can be observed in different Dog Breeds, it's not accurate to generalize that well-bred purebred dogs will always lay down with their hind legs stretched out while mutts will curl theirs under. Individual dogs, regardless of breed, may have different resting positions based on their comfort, personality, and physical build. Factors such as age, environment, and training also influence how a dog chooses to lie down. Therefore, it's essential to consider these variables rather than attributing behaviors solely to breed distinctions.
