Wooly Pomsky Grooming— when should I begin fur trimming, best shampoos, handy home accessories?

Im bringing home a 10week wooly pomsky. I read some comments about allowing their coats to develop and the range for breeds seems so vast. I didn’t see any tips regarding a pomsky. I love his coat but I want to have a better idea of best practices before it’s time or things I shld be doing now. All the dogs I’ve had previously were family pets with short hair— pits, and little guys. Any luck on wooly coat brushes or home accessories?
