If your dog has lost their entire nail, chances are you will know it. Many dogs lose their dew claws without even blinking an eye, so if you find a random nail in the dog bed, it's nothing to panic over. However, if the nail breaks off and it is bleeding, chances are it is bothering your pup and needs to be looked at.
What happens if a dew claw falls off?
If a dew claw is injured, you will often find that the animal may limp and cry out when you touch its leg. If the claw gets caught and torn off, expect there to be a lot of bleeding. This is because dogs' nails have quicks (the soft tender flesh below the growing part of the nail), which have their own blood supply.
Can you remove back dew claws?
Because front dewclaws serve an important purpose, they should not be removed unless there is a very good reason to do so. ... It is more common for veterinarians to remove loosely attached double or rear dewclaws to prevent injury.
