Dogs *may* scream if they are in pain, but dogs are also well known for hiding it; it's a survival technique common to many animals.

Other signs of pain include (but are not limited to):

• Whimpering or vocalizing

• Becoming quiet, withdrawn, and inactive

• Showing uncharacteristic aggressiveness when approached (an attempt to protect themselves from further pain)

• Holding the ears flat against the head

• Increased licking of a painful/sensitive area

• Decreased appetite

• Reluctance to walk, run, climb stairs, jump, or play

• Stiffness or limping

• Lagging behind on walks

• Unexpected reactions when touched

• Changes in personality

Dogs in good homes get very wimpy. Take my word for it. I take in rescue dogs - they enter intelligent, sly and stoic. They end up big babies, sleeping in our bed and crying and whining over every little thing. In that way, they are very much like humans. Anyone can see Trig’s dog is a well-fed, happy Black Lab.
