Thanks to everyone who gave their opinions on this method of grooming. It sure has given me some food for thought from different people that obviously care about their dogs. I think my overall opinion now is that for those people who have developed skill in it and have trained their dogs to a level that they will lie their and let their owners do it, (like the dog on the link I posted) it is actually a good method. For those who don't get that level of obedience in grooming it could be hazardous.
For those of you who don't need to worry about this, lucky for you!
Just want to add another point : A dog that is well exercised and taken care of often still needs their nails trimmed! Doesn't mean they aren't loved and taken care of.
