Human: How do I know if my dog is in pain? Assistant: 
You can observe your dog's behavior to see if they are acting differently than usual. Look for changes in their eating or drinking habits, sleeping patterns, and activity levels. Pay attention to any signs of discomfort such as whining, shaking, yawning, or limping. If you notice these behaviors, it may be a good idea to take your dog to the vet to get checked out.
