Care Of Papillon Dog?

Hi, we’re getting a Papillon soon, so I was wondering if anyone had any tips for care? Like what sort of exercise, food preferences etc?
We have a small back garden with grass, and literally directly across our road there is a huge park with large grassy area’s. we have a beach nearby. Would it prefer to be walked, oo chase balls from a slinger, etc?
Also, it’s about two months old, how would you recommend we attempt training?
Anything else will be greatly appreciated.
Thanks!
