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.

Ex Output:

So far I am really loving this product. I've used it twice since I got it and I haven't had to reapply yet. The only issue I had was that one of the bottle came with a cap and the other didn't. So it's hard to leave one at home and travel with the other one.

I bought a tumbler for a fallen officer friend. I honestly was worried the lids would fit. Lord and behold they fit great. So, not i was worried about the price and it really not going to leak. BAM! No leaks. I would recommend!!
