I've got those too...but I can't get them to go through Teddy's fur underneath, even with the blade protectors off! I usually get his underside trimmed at the vets when he goes in for a dental... Teddy doesn't like me touching him anyway so it doesn't matter if he hates me any more than he already does :lol: He's not nasty, just doesn't like being touched. :roll: Don't blame him though when I go and cut him up...:shock:
