Today Claire went to her first vet appointment. Everyone there loved her very much and said what a lovely little puppy she was. There was also much remarking on how well-behaved and even-tempered she was. The only mishap was when they took her temperature; she objected Very Strenuously to having the thermometer stuck up her ass, and expressed this objection by piddling on the floor afterwards. (Though that may also be partly that I had walked her there in the puppy-pack, and she's used to being let out of the puppy-pack into the side yard to go potty after a walk.) She did whimper a little when they put the ear-scope into her ears, but pretty much behaved.
At any rate, she's in perfect health, according to the vet -- literally, textbook perfect. She had a de-worming treatment even though they found no evidence of roundworms. (Vet says that there's a 20% false negative on that test, so better safe than sorry.) Next week she goes back for her first booster shot. They also trimmed her nails, and remarked on how well-behaved she was for everyone. (At least, everyone who didn't put thermometers near her butt, and that one was kind of expected.)
I asked about the diet, too. They say they've heard of breeders feeding puppies the adult food and giving yogurt, and that yes, it's generally fine. They do sometimes recommend moving to the puppy chow to help with some extra vitamins, but that it's really not a necessary step, and can be done gradually. At any rate, since she's in literally textbook-perfect health -- even the measurements are exactly spot-on the textbook values for a nearly-ten-week-old corgi! -- they don't think the diet needs to be changed, since she's obviously doing well on it.
I've also gotten her city dog license, and I've signed up to have the microchip ID put in when I get her little-girl operation done. I don't imagine she'd ever get loose and run away, but I'd really rather be safe than sorry and have it easy to get her returned!
Really looking forward to being able to walk her, though!
