After my dog had a bad, expensive, and miserable skin reaction and infection from the Costco Greenies, we changed to these Grain-free Greenies. Both dogs love these, have not had any issues whatsoever, and have remarkably fresh breath. That's pretty important, considering one is 12 years old and the other one loves to give us kisses!
We and our Pom Squad have learned that you get what you pay for, and it is worth the extra money to buy the real Greenies (after spending hundreds of $$ on vet bills and medicated doggy shampoos and skin treatments). We'll be back for more Teenie Weenie Grain-free Greenies!
