Query: good idea

but expensive JUST FOR DOG POOP!!!!!It's good to have one during travel especially if you have more than 2 SMALL dogs. Tho not a necessity. Bags are pretty darn small. Most people complain. End up getting poop on your hand lol.Those poop bags at dog parks are way more better. No container for bags but the bags are bigger and THICKER. These ones are SUPER THIN & SMALL.
