No one seems to know how, exactly, they gain loyalty levels (as in, what the formula is), and there are different theories about how to make it gain levels faster, but just use it for a while and it will eventually max out.
Actually one of the links on Petopia discusses this very thing(sorry can't check to link myself right now, so working off of memory).
The formula includes both xp and time.
Something like if your loyalty level is at 1, you have to have your pet for 30 minutes and earn 1% of the xp needed to level in order for it to gain the next loyalty level.
Then in order to get to loyalty level 3 you need to have had your pet for 1 hour and earned 5% of it's xp needed to gain the next level.
Even though you are at the level cap, there is still a to-next-level, xp requirement for both you and your pet, so it goes off of that number.
I'll look for it in a little while when I get more free time at work.
