Yeah you can stop using a crate later on if you want… I will say though, they’re actually really handy for going on holiday as the dog goes, ooh my crate, yay.
You do need to crate train properly though, which isn’t just sticking a puppy in and waiting for them to stop crying, it shouldn’t involve any crying - there’s loads of guides online for doing it step by step and it’s usually fairly quick with a puppy.
My big tip would be… because it seems to be hanging round despite science, ignore anything about dominance or being alpha or making yourself the boss. Dogs don’t live in packs, wolves don’t have a strict hierarchy, they’re a family and the ones in charge are in charge because they’re the parents not because they’re dominating the others and dogs aren’t going to try and take charge of your house because you let them go through doors in front of you or any other weird rule. Like teach them to wait at doors if you want them to wait at doors but it’s not going to make any difference to any other behaviour,
Also - there’s no set training every dog should have, it depends on what matters to you, some things are usually universally useful like drop, leave, wait, a solid recall… but I know people that don’t teach sit, they just don’t need it because they’ve got a solid wait and stay and they don’t care what position the dog is in when it’s doing it. Giving a paw, some people like it, some find it’s annoying because then a dog paws at you 😂
I fostered a Lhasa once who knew no commands at all, pretty sure he didn’t even know his name tbh, I tried doing some training with him, he didn’t even seem to grasp the idea of getting a reward for doing something - but he was a perfectly easy little dog because he just pootled about next to you on walks and was very chill indoors. So if you don’t want to teach something and you don’t need it, don’t bother. Equally nothing wrong with teaching a dog to do something just because you like it, mine both know boop and if you point a finger at them and say bang they’ll throw themselves on their sides, both completely pointless, I just like them.
