Not a fan of this, but it sounds about right for that way of kicking.
Of that method of kicking. Just pick up your heel, point your knee at what you want to kick and you will find that works fine. No reason to do the dog.You're not a fan of the drill or the person teaching it?
Ow.Absolutely best way to improve your kick...is to KICK! A lot...everyday.
Doesn't take special drills, just know how to perform the fundamentals and do them.
500 kicks a day and in 20 days you will have practiced 10,000 kicks.
