Dear Time Machine,
You might want to check Joanna's (the OP's) signature...
I DO use a slicker brush to prep for show day, though--she's exactly right that you don't use a slicker in daily grooming because it breaks topcoat. However, I've got great healthy minimally groomed coats on these dogs so I can slicker them on show day and it's fine. There's nothing like a slicker to get air between every hair and have the dog look just a little "poufed"--which is a look I DO like. Don't worry that I overgroom; these guys have genetically fab hard coats (one of the reasons I chose their breeder) and even after completely grooming out I can run my hands from tail to head and the coat falls back in exactly the place it should be.
Thankfully, I don't have to worry about teeth (raw diet) and nails are done once a week. I find that nails are still a problem with the Cardis--they just grow nails like bonkers. I've got them down to the absolute quick on each foot and they still peek out of the hairline, which drives me nuts. But I refuse to deliberately quick the dogs.
The only thing I even come close to quibbling on is the Air Force dryer--I just don't like that brand. I have a ChallengAir and am quite pleased with it. I don't use the SuperDuck just because I get nervous about putting heat on coats when they're groomed as often as I do; I just bring the HV to the grooming area at the show.
But I really DO get all nervous that I've overchalked and I blow it all out--I feel like Jesus is watching me puff all the chalk on and I end up feeling horrible and taking it all out again .
