The dog's itchy flesh is on the abdomen or back. As long as the owner scratches it, the dog will kick its legs to scratch it. It looks like a ticklish flesh, but it is actually a scratching reaction. This behavior is a conditioned reflex behavior of dogs, and they cannot control themselves.

Why do dogs have itchy flesh?

Dogs will kick their legs when being scratched. In fact, this behavior of dogs is a self-protection mechanism called the "scratch reflex", and it is an uncontrollable conditioned reflex. For some dogs, If the scratching force is more intense, the kicking reaction will be more obvious.

If there are parasites on the dog's skin, the itching sensation caused by these bugs will activate the scratching reflex, and the dog will kick off some of the parasites by kicking its legs.
