As the owner of a VERY dramatic husky, I know exactly what you're going through.
Like everyone else has mentioned, it's all a matter of getting your dog used to odd situations while keeping him calm and happy. The biggest thing I struggled with, with my dog is his nails. We adopted him when he was 4 years old, and he was already in full swing ready to fight tooth & nail to have them done. Huskies tend to be dramatic as it is, too, and if you let it go on long enough, they realize that screaming like you just lobbed off a foot will get them what they want, so it only gets worse! I'm assuming it would be the same for your guy. The best time to work on things like manipulating paws, ears, etc, is after a nice walk or play session where your dog's good & tired out. Then you need to hold on to paws and move them around, hold on to legs, etc. Something a lot of people forget is that while at first just touching them and holding them is a good start, you need to eventually be able to really, firmly grasp whatever you're working on, so things like getting a good grip to cut nails or draw blood is the norm. Also, always see if you can keep your dog under his threshold for freaking out, and if he starts to tug a bit, give some reassuring talk to calm him down, but don't actually let go of the leg until he's ok with it again. It's easier said than done, and it takes some time to get the timing right (resist him TOO much, and he's going to freak out, making it worse).
This is also something you want to work on every single day if you want to make progress. It's also something you should keep working on for the life of your dog, because it helps keep them accustomed to weird things, and calm and happy in odd situations.
