Inconsistent printing quality
Color: Beige
Sometimes the printed text has unclear edges, especially with small fonts, which look a bit blurry. When used for delicate decorations, it doesn’t look very professional.

excellent product, 100% digestible
Flavor Name: Bone (S), Size: 6 Count (Pack of 1)
excellent product, dog loves these. 100% digestible. not like rawhide that get stuck or can cause a blockage. the Vet said these are great, for a 10+ year old dog these help to keep her teeth clean. highly recommend

It’s best to get them fresh. Sometimes I’ve gotten them where you can tell they are old.
My dogs look forward to one of these nightly. It’s the best part of their day!

perfect treat
Flavor Name: Bone (S), Size: 6 Count (Pack of 1)
These are very limited ingredients treats and perfect size for a small dog but the cat likes them too. these are perfect size and shape for a little distraction so you call get a lil break. I have order couple bags and never passed day and color and quality look very fresh and peace knowing it is safe for my dog. These is no harsh chemical smell more like opening people turkey jerky. they are a lil pricey but for six pretzel or rings seem to be durable and gives me peace of mind . i highly recommend these for small dogs but the also have a wide assortment for bigger dogs . I highly recommend due to my positive experience.
