I throw away my dog’s poop in these blue bags (that I believe are biodegradable?) that i bought from Petco. (Not that it matters) Anyways, somehow the bags with the poop in it, don’t leave the bottom of the trash bins when the garbage man comes around. I have no idea how long this has been going on (I just noticed it) so do you know of a way to stop the sticking using the same blue bags? And why does it stick?
