Wow, it's early here and I also lurk /r/buildapc, so I was super confused what subreddit I was in for a second there! Awesomely formatted table.
Get a steel greyhound comb and a cordless Dremel for grooming. Get your puppy used to being groomed early on. Comb its fur, check its ears, run your fingers through its mouth, and Dremel its nails EARLY ON. I used to do my parents' corgi's nails with a clipper but switched to a Dremel after we met Drewbert's breeder and it's seriously a life changer.
My breeder dremels her puppies' nails (only the back ones at first) weekly from the moment they are born, so our puppy barely struggled when we first did his nails. It's also important to do his nails weekly so they don't get too long. As a result, Drewbert has the most perfect marshmallow paws and toe beans.
Also recommend you getting a shampoo. We have both a shampoo and conditioner for him. Our breeder recommended All Systems or Biogroom shampoos. For conditioner, we went with a True Blue Conditioner.
A Himalayan Chew also worked wonders with our puppy and he's in the middle of teething right now.
As for food, we were advised by every breeder we spoke with NOT to feed puppy food. Consult with your breeder and your vet (assuming you've picked a vet that is familiar with the breed) about this. Drewbert eats like a king and gets: Annamaet Encore, Vital Essentials Raw Beef Nibblets, a tsp of pumpkin purée in the AM and Annamaet Encore, 2 tbsp of plain low-fat yogurt, fish oil, 250mg Vitamin C, plaque-off in the PM.
