BEGIN YOUR ONE MONTH CHALLENGE

Register now and create a personal profile for your pet and sign up for the email support programme from our expert nutritionists.

The Challenge begins when you assess your dog's health with the interactive Assessment Card to record a 'Before' score. Come back online regularly to record her progress, and you'll be able to see for yourself the difference Purina ONE can make to your dog's health.

We'll hold the information securely for you, accessible only via your unique username and password, and remind you when it's time to complete each Card.

For those of you who are registering to obtain the challenge pack, the pack cannot be obtained online.

And once you've fed exclusively for one month, don't forget to tell us about your one month Success Story - we'd love to hear how you got on.
