Will Walmart accept this coupon?

I have a coupon for buy 2 get 1 free for cesar cuisine entrees for dogs. This coupon is directly from the cesar website, but it doesn't have a specified price for how much i need to pay for the 2 entrees to get one free. Walmart's coupon policy says internet coupons have to have a specified price for BOGO but I just want to know if they will accept this one ?
