13 warning signs your dog is in pain

Your dog literally trusts you with his life. Even so, he may instinctually hide his pain from you. It’s not because he suddenly doesn’t think you’re in his corner. The culprit, rather, is evolutionary hard-wiring that goes back thousands of years to your dog’s ancestral beginnings as a hunter-predator. “From an evolutionary standpoint, dogs who exhibited outward signs of pain were more at risk of attack from a predator. Over time, dogs learned to mask symptoms, which showed weakness, or vulnerability. From a survival perspective, many animals tend to hide outward expressions of pain,” says veterinarian, Jeff Werber. But you can still learn what your dog actually wants without having a full conversation.
