Roll over is one of the classic dog tricks, but there is more to this trick than just a little fun. It makes your dog use muscles in ways he normally wouldn't, which means he's getting a good workout at the same time. Keep in mind that teaching your Corgi to roll over puts him in a very vulnerable position during the roll. This means your pup must have a lot of trust in you, so before you try to teach this trick to your pup, you need to build that level of trust.
Building this level of trust or bond takes time. It means spending time playing with him, teaching him the basic commands, and just getting to know each other. Your dog will let you know when you have earned his trust. He will let you touch him anywhere on his body and will lay down near you and relax. When he reaches this point, you will be able to easily teach your Corgi to roll over.
Having taught your pup to do simple things like 'come', 'sit', 'stay', and 'lie down', you are ready to move on to something a little more advanced. 'Roll over' is a lot of fun to watch and your pup will love doing this trick for an enthusiastic audience. And yes, even Corgis can learn to roll over, it just looks a little more comical than with many other breeds.
This trick takes more than a single movement, which is why your pup needs to already know how to lie down on command. The reason for this is that rolling over is simply an extension of the down command, which will make it much easier for your pup to segue into rolling over on command. Take your time, be patient, and your Corgi will be hitting the ground flopping from side to side every time he hears the cue.
For this one, you won't need much in the way of supplies. The only thing you really need is a handful of nice chewy, smelly treats for your pup. You can use these as lures to help your dog understand what you are asking of him. You can also use them as rewards for when your pup gets things right.
