Training your dog to spin around is just one of those fun tricks he gets to do after he has been through basic obedience commands. Spinning in one direction and then having him spin in the other direction is often called 'dancing' for dogs. Whether he goes in one direction or two, when your dog stands up on his hind legs and spins around, heads will turn as well because you will have one smart and well-trained dog.
Imagine taking your dog out around your neighborhood and having him spin for neighbors. He will be the talk of the neighborhood -- your intelligent and cute dog who knows all the cool tricks. There are more benefits to teaching your dog to spin around besides all the great attention he will get. Teaching your dog to stand up on his hind legs and spin will actually strengthen his hind legs, give him some great exercise, and boost his confidence.
To train your dog to spin around while standing on two feet, you're going to have to have a dog who is used to standing on his hind legs. If your dog is not used to standing on his hind legs or does not have the strength, teach him to stand first, strengthening the legs for a little while before you actually begin training your dog to spin around. If you choose to have your dog spin around on all fours, you can start right away. However, if you expect your dog to be on his hind legs, strengthen his back legs for a week or two before you teach him to spin. Small dogs are pretty easy to train to spin around, however, you can train a large dog as well, especially if he's staying on all fours.
This is fun and easy trick to spin around will require some dedication and repetition. Be sure to bring lots of treats to your training sessions. Training in areas that are distraction-free will make it easier for your dog to focus and pay attention to you. If you need to do some strength training to get your dog up on his hind legs before training him how to spin around, just raise up him by enticing him with a treat to strengthen those back leg muscles every so often for about two weeks before you teach him to spin.
