I just bough it for a first time a few weeks ago and my dogs absolutely love it!!!
You should a see them all around me doing their trick with out me even asking them too,hoping to get an other chicken treat.
They get exited for any treats but this time it was out of control! lol
I don't know how long they are good for once the bag is open, so I put half of it in the freezer.
If you brake them in small piece, they are great for training!!!
And not expensing too.. really it's one of our new favorites treat here.
