You may want to get some baby nail clippers, puppy nails are super sharp, I snipped mine the day he came home.
Nylabone chew toys, best thing I ever got them, keep a probiotic in the house for upset tummies.
A brush, that puppy fur is hell, rounded baby scissors for hair trims around the eyes and clippers for the bum.
Some pea cleaner, also can be used to clean floors bedding blankets etc.
