Make Pet Bar larger?

[Warpig44]

Hello, new to WoW and new to your interface, infact I am new to all these mods, in any event I am a Warlock and I was wondering if it is possible to make the pet bar larger?

1680 x 1050 res, I see it etc it is just hard to click the icons in combat, I don't use the keyboard as I am lefthanded and find it easier to use the mouse.

Thanks for any help and keep up the great work.
