Any thick dog poop bags in the UK? My dog’s deposits could breach any bag known to man

TL;DR: Title

So I've got a Lab who produces absolute weapons of mass destruction on our walks around the local park. I've gone through about four different brands now and they all tear or leak, which is mortifying when you're trying to be a responsible dog owner.

The thin ones from Tes⁤co are useless and even the supposedly thick ones from Pe⁤ts at Home have let me down. Anyone found proper heavy duty poop bags that can handle a big dog's business?
