the 90-day guarantee

opened counts

we expect the pen to be opened. that's the point. if you started the protocol and it wasn't for your dog, you're covered.

the 90-day window

use the pen for up to 90 days across your first three pens. if you don't see a change you can describe, email us. we refund up to three pens. keep the pens — no return, no forms, no interrogation.

how to start

email hello@olddoglongevity.com with your order number. we confirm and issue the refund to your original payment method within 3 business days of approval.

what you get back

• a full refund of up to three pens to your original payment method.
• keep the pens. no return shipping, no restocking fee.
• if the order arrived damaged or defective, we cover the shipping too.

one honest ask

please email us before filing a chargeback. we approve honest requests quickly — a dispute takes weeks and puts our payment processor relationship at risk, which hurts every customer after you.
