Oh my word, just look at that little face! Love little Gigi.
Ok so.... food wise - Acana is an excellent food. Yogurt & pumpkin also great. How much are you feeding her, and how often? They need to eat more at that age. Are her stools pretty consistent and firm?
Rawhides are a huge NO for sure. I would stick to things that aren't easily destructed, because bullies are notorious for just swallowing things whole or semi-whole and this leads to obstructions. Antlers, nylabones all good. On Antler, moose or elk.
A decent amount of bullies need grain free, chicken free. Which you are already doing perfect on. For snacks or treats - you can do fruit, blueberries, bananas, apples, green beans, etc. Just make sure you cut them into bite size pieces

You probably won't be able to gauge her size until she reaches closer to a year old.
One thing that's important with bullies is their daily cleaning. You need to keep the wrinkles, ears, paws, and tail (under) clean. Daily is best to avoid any infections, etc. You can use plain jane baby wipes, witch hazel. Just a quick wipe in all those areas daily... we do it twice daily, but whatever you can manage will help keep her in tip top notch
Also, if you dont have this on hand at home, buy some plain benadryl to have on hand for allergic reactions

and some plain pepcid for belly issues.
