Just chicken please
Size: 3.5 Ounce (Pack of 1), Style: Chicken Chips
not bad and pup likes pretty much.
Love the size and fact "Chips". Package States "No artificial preservatives or additives" however, "Coconut Glycerin" added; personally would prefer this left out and "just"chicken.

Dogs love them
Size: 3.5 Ounce (Pack of 1), Style: Chicken Chips
I would have gave 5 stars, but you have to tear/cut into small pieces because they are hard for dogs to chew and swallow. Will buy again.

Dogs all beg for them!
Size: 3.5 Ounce (Pack of 1), Style: Chicken Chips
When I first received the package I was concerned about the small size of the crisps & the package itself. Not to worry! They are rather thick, and I had to half them for almost all of the dogs. They must be delicious because the dogs all gather around the corner of the treat table with the chicken chips! It takes them more than 2 seconds to chew, as well. I’m definitely reordering.

My dog loves these treats! Good ingredients, great size and value. And perfect for my picky little man. I also love that these don’t have a strong smell!
