When I first opened this box, I thought this supply will last forever! But then again, we don’t have a dog and only need them when the granddogs come to visit! If I averaged it out to only using one a day, it’s actually less than a year’s supply. They’re great to have, especially as Colorado is no longer handing out plastic bags in the grocery store, which is what we’ve used until now. The size is more than adequate for our wiener granddog to our Great Dane granddog and they’re very conveniently carried in a bone-shaped dispenser that easily clips to the leash, a backpack or a belt. The extra supply stores nicely away in the small box they were shipped in so I won’t lose them in the back of the closet. Love the fact that they are compostable and biodegradable, which DOES NOT mean you can leave them full and lying on the walking trails all over Colorado! They still need to be disposed of in the proper place.
