I have no patience for teaching proper nail manners either, because I hate long nails and just want them gone. I did try for a long time, but made little progress with my adult dogs.
That said, while none of my dogs are perfect, I dremel really quickly and they get a treat after each paw and that makes it slightly more tolerable for them. I never used a clicker, because that's too much for my clumsy self to hold all at once with the dremel.
I lay my dogs flat on their sides, and if they struggle and put up a fight, I just keep laying them back down and reward for what I want, then introduce treats and the dremel, and then just get it done basically. No real method. Just a "we're doing this, so I don't really care what you think" attitude, but I do try to make it somewhat positive. And then I just mastered how to hold each of them. The Dobermans are relatively easy, but Dance squirms a lot so I had to figure out a way to hold her so she couldn't keep pulling her paws away and trying to escape. She's horrid. And Journey's actually really easy somehow, so she doesn't count. Thank goodness. But yeah... for as positively as I do pretty much everything with my dogs, when it comes to general grooming and nails, I don't really have the patience to sit down and wait for them to learn to like it. I tried it, it took forever and ever and I barely got anywhere, and then I gave up because whether they like it or not, it's just something that needs to be done.
Sorry, that probably wasn't helpful at all haha. And I know it's a lot harder than it sounds, too, if you have a dog that struggles a lot.
