Auntie Scout sent in this question:
Can grade 2 children (He’s currently earning his Wolf Badge) earn Belt Loops? Can he earn the Pet Care belt loop if he hasn’t fulfilled all the Wolf achievements?
Any Cub Scout can work on the belt loops and pins in the Academics and Sports program at any time. This is a supplemental program though, so doing the achievements for the Wolf badge should be his first priority. But if he is interested in one of the areas in the Academics and Sports program, such as pet care, and he is making progress on Wolf, then yes, he should work on the belt loop.
The Academics and Sports program will be discontinued in May 2015 when the changes to the Cub Scout program are rolled out.
