The 90-day money-back guarantee.

Real supplements take weeks to show their full effect — so a 30-day guarantee is a guarantee you can't actually use. Ours runs the full window results take.

Use it daily for up to 90 days

Follow the dose on the label for your dog's weight. Consistency is what makes it work — and what makes the guarantee fair.

Not seeing a difference? Tell us.

Email or message us any time within 90 days of your first order. No phone trees, no interrogation — a human reads it and replies.

Full refund. Keep the tub.

We refund your purchase in full to your original payment method. No return shipping, no restocking games — donate any unused chews or toss them.

The fine print, in plain English

· Covers first-time purchases of any product, one guarantee claim per household.

· Applies to orders placed on this site. Amazon, Walmart, and Chewy orders follow those stores' return policies.

· Subscriptions: the guarantee covers you, and you can also skip, pause, or cancel anytime — separately from any refund.
