Five named probiotic strains: Bacillus subtilis, Bacillus licheniformis, Bacillus coagulans, Lactobacillus plantarum and Lactobacillus acidophilus, at 5 billion CFU per serving. Alongside them: digestive enzymes, prebiotics to feed the good bacteria, a pumpkin and flaxseed fiber blend, gut soothers like Greek yogurt and fennel, and skin antioxidants like blueberry. No corn, no soy, no artificial colors. Chicken flavored. Contains Greek yogurt (dairy). Every amount is printed on the label, nothing hidden.
Give daily with food: 1 chew up to 35 lb, 2 chews for 36 to 65 lb, 3 chews for 66 to 100 lb, 4 chews for 101 to 120 lb, 5 chews over 120 lb. Start with half the amount for the first few days so the gut can adjust. One tub holds 60 chews. On subscription you pick your dog's size and we match the supply: bigger dogs get more tubs per delivery, so you never run out.
Free US shipping over $35, and subscriptions always ship free. Not happy within 60 days? You get 100% of your money back. No partial refunds, no return-the-package hoops, no questions. Subscriptions cancel in one click, and nothing ships after you cancel.
Take the label to your vet, we like it when you double-check us. Every strain is named on the label with the CFU count, so your vet can see exactly what your dog gets.
In one click, from your account. No chat, no phone calls. Nothing ships and nothing is charged after you cancel. Prefer email? Send us one line and we do it the same day.

"I like that Wendell is honest about the timeline. Digestion settles first, skin follows over weeks. That's how the gut actually works."

"Named strains and a guaranteed CFU count. That's exactly what I look for in a canine probiotic, and Wendell puts both on the label."

Reviews describe individual experiences of real customers. Results vary from dog to dog and are not guaranteed. Wendell supports normal gut and skin health and does not treat or prevent disease.
Skin starts in the gut. So that's where Wendell starts.
Most itch that keeps coming back isn't a skin problem. It's the gut out of balance. Wendell puts the good bacteria back, every day, so the skin can calm down from the inside.

What the research says
Backed by studies, not by us.
We don't have a lab of our own. Wendell is built on what veterinary research already shows about the gut and the skin.
Itchy dogs have a less diverse gut than healthy dogs.
Animals, 2022 · comparison of atopic and healthy dogs
In every clinical trial reviewed, dogs given daily probiotics scored lower on itch and skin severity. Modest, not a miracle.
Journal of Veterinary Medical Science, 2025 · review of 5 trials
The more out of balance the gut, the worse the skin. Restoring the balance went hand in hand with calmer skin.
Frontiers in Veterinary Science, 2025 · probiotics and gut balance in dogs
Wendell supports normal gut and skin health. It doesn't treat or prevent disease. If your dog is under treatment, keep following your vet's plan.
Your questions, answered honestly.
Digestion usually settles first, often within a week or two: firmer stools, less gas. Skin and coat take longer. Give it 6 to 8 weeks of daily use, because the skin only changes after the gut does. That's why you get 60 days, not 7.
Three usual reasons: too little good bacteria, sugar-first recipes, or stopping before week 4. Wendell gives 5 billion CFU from 5 named strains, every day, and we ask you to give it 6 to 8 weeks. If it doesn't work for your dog, you get your money back.
Wendell works alongside your vet's plan and never replaces it. Don't stop any medication on your own. Take the label to your vet: every strain and amount is printed on it, so they can check it in a minute.
It's a soft, chicken-flavored chew, and most dogs take it like a treat. If yours refuses it, that counts: tell us within 60 days and you get 100% back.
Start with half the daily amount for the first few days so the gut can adjust, always with a meal. The recipe is gentle, and the 60-day guarantee covers you either way.
On subscription a tub is $29.95, that's $0.50 per chew. A dog up to 35 lb needs 1 chew a day, so about $1 a day. Bigger dogs need more chews, and we show you how many tubs that is before you buy. No surprises.
Wendell contains Greek yogurt (dairy) and chicken flavor. No corn, no soy, no artificial colors. If your dog has a chicken allergy, this isn't the right fix, and we'd rather tell you now.
Yes, Wendell is made for daily use. For puppies under 12 weeks or a dog with a health condition, check with your vet first.
If you and your dog aren't happy within 60 days, you get 100% of your money back. No partial refunds, no sending the tub back, no questions. Email us and it's done.
Order for the bigger dog. After checkout, add tubs in your account and both dogs are covered in one delivery. Every tub is $29.95 on the same schedule. Not sure how many? Email us and we set it up.
