Limping is a common sign of pain in dogs. If your dog is limping, it could be a sign of an injury, such as a sprain or a fracture.
Dogs will often cry or whine if they're in pain. This is their way of trying to communicate that something is wrong.
A change in appetite can also be a sign of pain in dogs. If your dog suddenly starts eating less or more than usual, it could be a sign that they're in pain.
A change in behavior can also be a sign of pain in dogs. If your dog is suddenly more aggressive, withdrawn, or lethargic, it could be a sign that they're in pain.
Dogs in pain may also be restless. They may pace back and forth, lick their paws excessively, or have trouble sleeping.
Dogs in pain may also have a decreased activity level. They may not want to play or go for walks, and they may prefer to lay down more often.
Dogs in pain may also make different vocalizations than usual. They may bark or whine more than usual, or they may make a high-pitched yelping sound.
