This is a set of two sprays for training your dog (biting, excessive barking). I used them a few times after purchasing, but both still have plenty remaining. I'm selling them because I no longer need them! How about using them to train your dog? ^^ - Expiration Date Ama-gami Non (Biting Non): 2028.7 Muda-bae Non (Excessive Barking Non): 2028.2
