Query: Hey is for horses and so are these

Bought these for a couple of medium sized dogs. I could pick up their poop for a week in the same bag. It's a terrible waste of plastic and they aren't even environmentally friendly.Product description says "Refill bags fit any standard dispenser.", however I could only fit a single bag inside of my bags-on-board dispenser and that was squishing it into a little ball.If you have a horse, a great dane or a mastiff then you'll love these. Otherwise stick with a smaller bag.
