My 3 Vote Yes
Flavor Name: Bacon & Apple, Size: 5 Ounce (Pack of 1)
All three of my dogs LOVE these! There aren't a lot in the package for money. But the jerky pieces are big enough and soft enough that I was able to break them to make them last a little longer.

Change in quality
Flavor Name: Bacon & Apple, Size: 5 Ounce (Pack of 1)
I have purchased these for a few years directly from Whole Foods, and was excited to see that it was now available from Amazon. The quality has been changing recently. I have these on AutoShip and they’ve gotten increasingly darker in color which I’m assuming means cooked more or longer and they’re incredibly hard now. These are supposed to be a soft chew and I have a Chihuahua and even cutting them up, he can barely eat them. Hoping this feedback gets back to the right people in quality control.
