I have 3 rescue dogs, all different sizes, when I need to use Revolution, I need to buy 3 different size packages for different weight dogs The cost comes to about $400 twice a year. Receiving awards would help, but Zoetis is greedy, does not easily return rewards. I should receive $45 every 6 months from Zoetis I received a $5 gift card from them Zoetis told me it had a greater value, but this was Not the case, Dishonest User's recommendation: Don’t buy from Zoetis or don’t expect your rewards.
