As another reviewer mentioned, these treats are CRUNCHY!. I like them for 2 reasons..my dog can't just "woof them down", she has to chew them, so they last..and I like that the cruchiness may be good for her teeth. The treats are small, but again, are crunchy...I'm glad I found these. She loves them and I like giving them to her.

This is by far the best hot cocoa I have found yet for the Keurig. I love the assortment and the peppermint is my favorite. I would give these try for sure if you are looking for some hot cocoa K-cups. All the other selections for hot cocoa that I have tried were just okay tasting. These are AMAZING!!!! LOVE THEM! I will order these for sure again!

Only three jars came in a form edible to babies.  The rest of them were filled will a clump of spongy mush that would not mix with the water.  It also had a brown color and not the yellowish brown like the jars that had the good mixture. Pretty disappointing and a waste of money.
