Dogs with tapeworms will often scoot across the floor. There are a few different varieties of tapeworms. Fleas carry tapeworms, so if your dog has fleas, or had fleas, there is a good chance he could have tapeworms (see flea write-up). Also if the dog eats the flea he could have tapeworms.
Ballet dancing is a great workout for the whole body. Classical music is often used in ballet lessons. There have been studies that confirmed the positive influence of classical music on our overall wellbeing, especially that of the Baroque era and Viennese Classicism (particularly Mozart). Ballet practice improves flexibility and muscle strength and tone; it has the advantage of working the entire body.
