Royal Canin Veterinary Diet Mobility Support Large Breed Dry Dog Food

Daily feeding recommendations may be divided into 2 - 4 meals.

We recommend at least a 7-day transition before you begin feeding the new food exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet’s digestive system to smoothly adapt to the new food.

2. At checkout, you’ll be asked for required information. Enter your pet’s name and your vet’s name & telephone number.

How will you contact my vet?

Our Veterinary Diets team will personally contact your vet for approval. If your clinic needs more information from you or recommends a different diet, we’ll let you know immediately.

Does it help if I send you my veterinarian’s authorization?

Yes! If you have a paper copy of your vet’s authorization, email a picture to vetdiet@chewy.com, start a chat, or fax it to 1-800-619-7973.

Can I use a veterinarian’s authorization if it was written by a veterinarian out of state?

Of course! We can accept valid authorizations from anywhere in the United States and Canada—that includes US territories, like Puerto Rico.

Why do I need a veterinarian’s authorization?

Veterinary Diets are formulated with the precise ingredients and nutrients needed to address specific medical issues. If you don’t have a paper authorization, no sweat—once you provide your vet’s information, our team will take over.

Can someone else (such as a caretaker or family member) place an order for my pet?

Yes, but we’ll need them to provide us with the full name of the pet’s owner’s name via phone, email or chat after the order is placed, so the clinic can locate your pet’s records when we contact them.

How can I help expedite my order?

Just follow these simple steps:

1. Create your pet’s profile on Chewy.com.
2. If you have an Autoship scheduled, but you’re running low on your Veterinary Diets, contact us ahead of time to let us know if you have a new clinic or if any authorization information has changed.
3. If you have an authorization handy, send it to us before you order—by sending an email to vetdiet@chewy.com, starting a chat with one of our experts, or faxing us at 1-800-619-7973.

Do I need to set up a pet profile?

We recommend it, but it’s not required. You can create your pet’s profile by logging in at Chewy.com, hovering over your account, and choosing “pet profile.”

Do authorizations expire?

Yes. Your vet will tell us when your authorization will expire and how many times we can send before they’d like you to check back in with them.

Can I set up automatic refills?

Yep! Sign up for Autoship and we’ll automatically ship your Veterinary Diets for as long as your authorization allows. If you run out of refills, or your authorization expires, we’ll automatically contact your vet for a new authorization. If we hit any bumps in the road, we’ll let you know right away.
