Like other reviewers, I'm disappointed they changed the formula. My dog has a bunch of problems and pees/poo's himself everytime he goes out. I use these in-between baths to keep him clean and they used to be a LIFESAVER. With the new formula he doesn't get nearly as clean as he used to and he still smells. They work and I be see soils coming off, just not completely.

These used to be the best wipes. But they changes them. We had a subscription and the last time they can the packaging was blue, like in some of the other new reviews. Checked the ingredients list to see if that had changes, and they had added a couple ingredients, but they were at the end so we figured we'd at least try it. Well, my baby has never had diaper rash... We give this new one a try and she cries when we wipe with them, and got diaper rash really bad by the end of the day. Horrible! So disappointed because we loved these wipes.. also pretty upset with Amazon for still advertising them as the old ones and randomly sending us these new ones :(

Works ok, didn't hold up as long as I figured. Used to hold a Cobb accessport. Help up for about a week in cold weather. May work better in the summer time
