Any sudden changes in behavior, such as increased aggression, withdrawal, or uncharacteristic quietness, can be indicative of pain. Dogs may become more irritable when they're experiencing discomfort.
A noticeable decrease in your dog's overall activity level, reluctance to engage in play, or a sudden lack of interest in walks and exercise may be a sign of pain.
Dogs in pain may show a loss of appetite or changes in eating habits. This could manifest as eating less, eating more slowly, or avoiding certain types of food.
Observe your dog's gait for any signs of limping, stiffness, or difficulty getting up and lying down. Changes in mobility can indicate musculoskeletal pain or joint issues.
Dogs may lick, bite, or chew at a specific area excessively when in pain. This behavior may be an attempt to soothe or draw attention to a painful spot.
Pay attention to your dog's facial expressions. A tense facial expression, squinting, or a pained look in the eyes may indicate discomfort.
Whining, whimpering, yelping, or growling can be vocal expressions of pain. However, some dogs may become unusually quiet when they're in pain, so any change from their normal vocal behavior should be noted.
An increase in restlessness, difficulty settling down, or changes in sleeping positions may suggest discomfort. Dogs in pain may have trouble finding a comfortable position to rest.
