this is the winner so far, but it's literally $50 and it's made by an idiot who thinks it's very important to rescue overseas dogs from "the meat market" so i really would like to do better
Hey I have that! I like it a lot. Mine has Velcro on the front pocket instead of a zipper. The fabric does get greasy/stained by treats though, and the one time I washed it the hinge got really weird about opening so I’m afraid to wash it again 😅
Mine is an RC Pets Quick Grab Treat Bag, and it's held up surprisingly well to greasy nasty treats in it. I try and keep the awful stuff inside a Ziploc bag (which then goes into the fridge when I get home), but sometimes I don't remember and then it's just handfuls of chopped shredded chicken in there. I've machine washed it once and it was totally fine. Tried to remove the clip first but couldn't figure out if that was possible, so in the end I just tossed it in there and hoped. I have also successfully washed it in the sink with castile soap.
There is definitely not room in it for multiple tennis balls AND treats, though.
It's got two internal compartments for treats and the external zipper for clickers etc; I have a Beco Pocket on the waist strap for mine to hold poop bags. Works great. (I tried clipping it to one of the front loops but that fucked with the weight distribution in a way I didn't like.)
Oh, yesterday at recall class I heard the best suggestion for really high value stuff I've ever seen, which is to cut a hole to access the larger pocket that the inner pockets sit inside and slide frozen condiment packets or other small frozen items into it to keep your treats chill. Genius.
Tilly going to work with me has meant that my bait bag gets way heavier use than I've ever had before, and I've really appreciated how that one holds up.
That one with the one-hand stay-open hinge is well worth the $50 IMO (my review of my first one), such that when my hinge broke after 4 years of daily use for dogs & horses, I immediately bought another. Tristan’s Fetch and Tug Buddy still has his original one getting lighter daily use, and it's in great shape.
Mine from 2022 and TFaTB's from 2018 (the newer front zipper is a lot easier to use than the original velcro)
I keep big horse cookies loose in mine, use a silicon treat pouch for holding mixed dog treats, and can still fit a couple of tennis balls too.
I use the back pocket for my phone, keep a whistle clipped to it because my dogs sometimes can't hear across a field, keep emergency meds in one of the side pockets. There's a utility knife in the front pocket for emergencies. It's so easy to just grab and clip on as I head out the door.
