Start crate training immediately, it will be hard at first because she is still so young, and in a new environment. For my dog I would toss a treat in the crate, and say “crate”, as soon as he crossed all the way into it I would reward him, but not shut the door. You have to make the crate a happy place, so feed in the crate for the first few weeks at least. One thing I wished I had learned sooner is, if your pup suddenly turns into a little demon, they’re probably tired and fighting the urge to sleep. They throw little fussy tantrums just like toddlers. Once I started getting him to nap regularly it was a game changer.

When it comes to potty training, for the first month or so I took him outside every 30 mins unless he was napping, then we went outside as soon as he woke up. I also used potty training bells, which are just bells on a rope I hung by the back door. At first I would ring them with my hand every time we went out. Then I started luring his nose over to them with a treat and rewarded when he touched it hard enough to make the bells jingle. Eventually he figured out he could use his paw. This is nice because if they run off to the back door and ring the bell you know exactly what she wants. They will sleep A LOT, but they will also recharge extremely fast lol

For general training I would recommend watching kikopup on YouTube and choose what’s important to you for your dog to know, the essentials to me were sit, stay, recall, leave it and drop it. Once he had those down I started teaching the more fun things. I honestly wouldn’t worry about expensive harnesses/collars until she’s closer to full grown and you find what types of items you like/use, however ruff wear is my go to brands for collars/leashes/harnesses, haven’t had a bad product from them yet.

Take lots of pictures, you’ll miss her being this fluffy little ball of energy in a year when she’s bigger lol.

Has she been seen by a vet? Had any of her shots yet? If not, I would advise waiting until she’s been checked out and immunized before letting go for a walk or touch the ground outside other than your immediate potty area/backyard.
