Your puppy is so cute! His parents aren't too bad looking either
lol. You're an Amazon addict? Me too! I think I bought about 95% of my puppy/dog supplies on there except for id tags and buddy belt harnesses (I bought those from sellers on YT). These are the clippers I have. They're mid range price and cordless so I don't have to worry about getting tangled/tripping lol. Mine don't get hot, but I only use them to shave stomach hair and finish off sanitary cuts. So that's about 10/15 minutes they're on max, once you get the hang of it the less time you'll spend on it.

When the adult coat comes in depends on the puppy, Rasta's started coming in about 9/10 months but your boy's could be sooner.
