Only one ingredient
Size: 1-Pack (0.5 lbs)
I really like that. The product had only one ingredient which was sweet potatoes. They were well packaged in a reclosable bag. However, my dogs (a Morkie and a Malti-tzu) had no interest in them and would not even try it. I passed it on to someone else to try for their Shiba Inu.

Usually good, but not this time
Size: 1 lbs
The last bag was very hard but I am softening them up with “sugar bears”. When we first started getting them you could easily cut them & my girl loved them. Then we got a bag that molded within a couple weeks. I tried others but my girl didn’t like any as well as these. Eventually I came back to Dave’s & it was fine until this last bag & she wouldn’t eat them.

Good value
Size: 1 lbs
A good value. The treats are a variety of sizes and my dog really likes them. They are fairly chewy so he doesn’t gobble them right down. I like that they are a healthy treat, since he can eat high fat or high sodium treats.
