You, your dog, and anyone else can do any and all of the "maintenance" on your RV-12 E-LSA or E-AB. However, to do the annual Condition Inspection on an E-LSA owned by you, you need to have taken the FAA-approved 16-hour course. If you built your RV-12 as an E-AB, then you as the builder can do the annual Condition Inspection if you qualify for the appropriate repairman certification. There are more permutations of this for second-hand owners, etc.
