Is it true that mutts would sacrifice themselves to protect there owner?

While mutts, or mixed-breed dogs, do exhibit strong bonds and loyalty towards their owners, the likelihood of an individual dog sacrificing itself to protect its owner varies and cannot be generalized.

Factors such as the dog's personality, training, and specific situation play a significant role in determining its response. Some dogs may display protective behavior towards their owners out of loyalty and affection, while others might react differently depending on their perceived threat level and their own survival instinct.
