Eukanuba has launched its 28-Day Challenge, asking dog owners to feed their pets any Eukanuba formula for 28 days to "find out for themselves what a difference a premium Eukanuba diet can make," according to Manuel Miyar, the company's associate marketing director.

Interested consumers can sign up via Facebook, where participants can also enter a contest where one dog will be crowned the "Challenge Champion" and appear in Dog Fancy magazine and select Eukanuba advertising. “We all have such a passion for dogs and are committed to providing extraordinary nutrition so they look and perform at the top of their game,” said Miyar. The deadline for entering the challenge is June 12; the deadline for the champion contest is April 30.
