Give it a sooth bell and use it for most things.(battles, pokeathlon, run with it, etc.)
The way I do it is by giving the Pokemon you want happy a sooth bell, this will make the Pokemon grow happy fast. Then every day give the Pokemon a message at Veliston (spelling?). Also make sure that it's the first Pokemon in your party and never put in the PC boxes.
You can make it happy by treating it to spa.
You can make it happy by training it a whole lot. usually it takes a Pokemon 20-30 LVs to be fully happy.
you have to run around with it lots. also battle with it. those two things make Pokemon happy.
Yes but it shouldn't make you happy.
Just use them alot in battle and give them good berries and that should make them happy
