2. Being More Vocal
One of the signs a dog is in pain is increased vocalization. Is your dog making more noise than usual? If so, he could be trying to tell you that he’s in pain.
Look out for a sudden increase in whining, growling, barking, or other kinds of vocalization. And if your dog is being more vocal than normal, check him over to see if you can identify any areas of his body that may be in pain.
Always be sure to inspect your dog’s body for painful areas as gently as possible to avoid causing further harm.
