Digestion often settles within a week or two. Skin and coat take longer: give it 6 to 8 weeks of consistent daily use, since the gut-skin connection builds gradually. Results vary from dog to dog, and the 60-day guarantee covers you while you wait.

It goes by weight: up to 35 lb, 1 chew a day · 36 to 65 lb, 2 chews · 66 to 100 lb, 3 chews · 101 to 120 lb, 4 chews · over 120 lb, 5 chews. Give daily with food; start with half the amount for the first few days.

Yes. Wendell is made for daily use in a GMP-certified US facility and every batch is tested. As with any supplement, check with your vet if your dog has a health condition or is on medication.

One chicken-flavored soft chew packs six jobs in one: probiotics (5 named strains, 5 billion CFU), digestive enzymes, prebiotics, soothing fiber, gut soothers and skin antioxidants. No corn, soy or artificial colors. Please note it contains Greek yogurt (dairy).

Most dogs take it like a treat: soft, bone-shaped and chicken-flavored. If yours doesn't, tell us and we'll make it right with the 60-day guarantee.

You pick your dog's size and we match the supply: bigger dogs automatically get more tubs per delivery (every 2, 3, 4, 5 or 8 weeks), so you never run out. Each delivery is $29.95 per tub instead of $39.95, and shipping is free.

Any time, in one click, from your account. Skip a delivery, change the timing, or cancel. Nothing ships and nothing is charged after you cancel. No emails, no hoops.

US orders ship free, are processed within 24 business hours, and typically arrive within 3 to 5 business days. You'll get a tracking link by email.

If you and your dog aren't happy within 60 days, you get 100% of your money back. No partial refunds, no return-the-package hoops, no questions. Just email hello@wendell.dog with your order number.

Wendell plays well alongside most daily supplements. If your dog takes prescription medication, run the label past your vet first. That's what it's printed so clearly for.

Wendell is formulated for dogs. For puppies under 12 weeks or any pet with a health condition, check with your vet first.

Cool, dry and out of your dog's reach, with the lid closed. No refrigeration needed.
