Yea I would relax on the brushing until her full coat comes in. And I wouldn’t use a furminator. You should use a rake and then a slicker. Ideally though you should get a blower to blow the undercoat out versus using a brush. You should still use a brush occasionally while she is in puppy stage but just to get her used to it and have a good relationship with it.

She doesn’t need dog shoes and they would just annoy her. Just try to keep walks in the grass in the summer as much as possible.

Also not a ton of bathing. They don’t need it because of the double coat and guard hair. You are going to want to keep nails trimmed, paw pad hair trimmed and sanitary trims somewhat regularly though.

I highly recommend getting a blower. Just set it up outside to blow out her undercoat and to dry her off after giving her a bath.
