I bought a bag of these and kept it sealed up---but they dried out really fast. The dog liked them alright---the cats liked them better. I was not too impressed with this treat...but I could see how some dogs would love them.
Re your saying the treat dried out fast: the zip on this bag can split away from the main bag rather easily I think. The zip feels like it's working ok. To check, press the bag after sealing to find if any more air is coming out. And pressing all the air out when sealing the bag is a big help.
