Six jobs in one daily chicken-flavored chew, built around the gut-skin connection.
We recommend at least 2 months of consistent daily use. Gut first, then skin.
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.
Wendell is vet-reviewed, and we like it when you double-check us. Every strain is named on the label with its CFU count, exactly what vets look for in a probiotic. Snap a photo of the label and bring it to your next visit.
How to give it, and what the first two months usually look like.
Give with a meal. Start with half the amount for the first few days so the gut can adjust. One tub = 60 chews: from two months for small dogs to about 12 days for the biggest dogs.
Digestion settles first — owners report firmer stools and less gas, often within two weeks.
The gut-skin connection shows — less itch-driven licking and a shinier coat.

"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."

"Most owners wait too long to support the gut. One consistent daily chew is the easiest habit I recommend for digestion and skin alike."

"I like that Wendell is honest about the timeline. Digestion settles first, skin follows over weeks. That's how the gut actually works."
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.
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.
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.
The ingredients are food-grade and the formula has a wide safety margin, but if a dog gets into the tub and eats a lot at once, an upset stomach is possible. Keep the lid closed, store it out of reach, and contact your vet if you're concerned.
Wendell contains Greek yogurt (dairy) and chicken flavor. No corn, no soy, no artificial colors. The full ingredient list is on the label and on this page.
Cool, dry and out of your dog's reach, with the lid closed. No refrigeration needed.
Wendell is formulated for dogs. For puppies under 12 weeks or any pet with a health condition, check with your vet first.

"I love that I finally buy one thing instead of four. Her stomach is calmer, her coat looks better, and the label actually tells you what's in it."

"Week one: firmer poops, way less gas. Week five: the constant paw-licking has calmed way down. I changed nothing else, so I'm giving Wendell the credit."

"The gas. THE GAS. It's gone. Three weeks of one little chew a day and my couch, my blanket and I can finally breathe again. Otis remains unbothered and adorable."

"Our vet recognized every strain on the label, which is why I picked Wendell over the big names. Eight weeks in, her coat has honestly never looked better."

"He thinks it's a treat. Sits by the counter every morning waiting for it. His stools are finally consistent, and the yeasty smell is fading."

"Tried three separate supplements before this. One chew instead of a cabinet full, and his stomach hasn't been this settled in years."

"Tiny dog, dramatic stomach. Every new food was a gamble until this. Two weeks in, the midnight gurgling stopped and breakfast stays down. He now stares at the cupboard where the tub lives."

"Shedding season used to mean hot spots and a miserable, itchy dog. This year her undercoat came in softer and she finally stopped gnawing her flank. Husky owners, you know what a big deal that is."

"The night-time scratching was wearing us both out. A few weeks in and the licking has really settled down. He eats it like a treat too."

"Picky eater approved. Scout inhales it like a treat, and her merle coat has honestly never been this glossy — our groomer asked what changed."

"Six weeks in and the paw-licking has really eased off. Walks are happier for both of us, and he comes running when the tub comes out."

"Buddy is 11 and picky as they come. He takes Wendell like candy, and his digestion has been noticeably calmer since week two."

"Adopted Leo with a nervous stomach — every road trip was a gamble. Eight weeks of Wendell and he's a different passenger. Calm belly, shiny coat, zero drama."

"Skeptical after wasting money on two other brands. The 60-day guarantee got me over the line. I stayed because the itching genuinely eased off around week six."
"Allergy season came and went without the usual biting frenzy. First year ever. I kept waiting for it to start and it just... didn't."
"My vet read the label and said 'this is actually good.' Every strain named with a count. That's why I picked Wendell over the big names."
"Theo is 11 and back to begging for longer walks. Firmer pickups too, which the whole street appreciates."
"Third probiotic we tried, first one that stuck. She eats it before her actual dinner. Subscription runs itself and support answers like real humans."
“Two weeks in: normal poops for the first time since we adopted him.”
“The 2am scratching stopped somewhere in week four. I didn't even notice until my husband did.”
“Smells like a treat, works like a supplement. He beats me to the kitchen every morning.”
“Our frenchie's gas could clear a room. Could. Past tense.”
“Our vet suggested a probiotic after antibiotics upset his stomach. This one had actual counts on the label, so we picked it. Zero regrets.”
“Skeptic here. It took five weeks, but the paw-licking genuinely faded.”
“One chew replaced three different powders I was sprinkling on her food. She's happier, I'm happier, my wallet is happier.”
“Her coat gets compliments at daycare now. That never happened before.”
“Started for his stomach, stayed for the shine. His coat looks freshly groomed all the time.”
“Picky chihuahua approved. If Pixie eats it, anything will.”
“Road trips used to end in a messy crate. Three months on Wendell and he travels like a champ.”
“I like that they tell you it takes 6 to 8 weeks instead of promising overnight magic. It took six. Worth it.”
“The subscription is actually painless. Skipped a month while we traveled — two clicks, nothing shipped.”
“Foster mom here. Every itchy intake starts on Wendell now. The difference by week six sells itself.”
“My senior girl started finishing her meals again. Small thing, huge deal.”
“Bought the one-time tub to test it. Subscribed before it was half empty.”
