Pet question

[Numb]

Hi guys,
It's been a while! Just a few quick queries on the new pet skills. How many skills can 1 pet equip? I already have the Auto Move Skill but does the Expanded Auto Move Skill and the Auto Feed and Movement Skill stack? I'm having a hard time understanding as one is a normal 3x range expander, and the other allows your pet to navigate multi-levelled maps. If they don't stack, which is better?

Thanks guys.

They all stack, you can load every skill onto one pet if you'd like.
