OK. solve this:
My 2 dogs love this treat. When my oldest (male) was younger, he would sit down, stand up, go down, roll over, etc. and do every trick in his repertoire before I even gave him a command whenever I pulled out a bag of the liver biscotti. My female also loves this but she's a little less silly. Also, this has never upset their stomachs nor caused allergic reactions. I finally had to find a place that sold this in bulk (i.e., 5 lbs. bags) since I was going to the store ALL the time to buy more of these. I also stuff their Kongs with a combo of these and their regular kibble and some pumpkin and freeze it. I highly recommend this treat.
