Preferred Treat Bags?

Hey all! I’m on the waitlist for my service dog and I’m trying to decide what treat bag to use.

I am an ambulatory wheelchair user, so if I have a bag that can swap between both that would be nice, but not necessary. I have a clip on silicone one that I like on my chair well enough, but I work about it not being secure enough clipped onto a leash or a pocket while standing. However, obviously hip bags are more bulky.

I’m also plus-size, so a hip bag would have to sit basically on my waist rather than my hip, which aesthetically can look a bit strange!

Thoughts, feelings, vibes? Interested in opinions with the functionality, ease of use/carrying around, and looks!
