Check your dogs for fleas. This is a typical area where fleas congregate. If you have not done so, start flea prevention on all of your dogs and regularly vacuum your house and furniture as well as non-carpeted areas, wash bedding in hot water. If the itching does not stop after a few days (after using flea prevention), take your dog to a vet for an exam as there may be other causes such as a fungal or bacterial or mite infection.
