Nearly 1 in 3 Dogs Have Had a Gut Issue in Their Lifetime*

It's more common than most people realize. And more connected than most people think. Because the gut doesn't just affect digestion. It affects immune health, energy, skin condition and overall well-being.

If something seems off, the gut is usually where it starts. That's what we built Probiotic Chews for.

Benefits

Less reacting to every meal, treat or change in routine. A stomach that settles and stays settled.

Fewer bad days. More predictable digestion. A dog that just seems more comfortable in themselves.

Getting sick less often. Recovering faster when they do. A dog that's more resilient day to day.

Consistent, normal and exactly what you want to see.

Results Timeline

Our supplements are built for the long game. The more consistent you are, the harder they work.

WEEK 1LAY THE GROUNDWORK

From the first chew, the good bacteria are making their way to the gut and getting established. The prebiotics are feeding them. Marshmallow Root is preparing the gut lining they'll call home. Nothing to see yet, that's normal. The foundation is being laid with every serving.

WEEKS 2–3SOMETHING'S STARTING TO SHIFT

You might catch it on the morning walk first. Stools that are a little more consistent. A stomach that seems to be settling. The good bacteria are growing and finding their balance, and for some dogs, it starts to show earlier than you'd expect.

WEEKS 4–6YOU'LL SEE IT. THEY'LL FEEL IT.

More predictable digestion. Less reacting to every little change in food or routine. A gut that's starting to work the way it should. Some dog people also notice their dog seems more comfortable overall – more energy, better coat condition. The gut runs more than you think.

WEEKS 6–8IN FULL FORCE

A balanced, well-nourished gut microbiome supporting digestion, immune health and overall well-being every single day. This is what the long game looks like. Don't stop now.

Remember: Every dog is different. Size, age, where they're starting from – it all plays a part. Daily use is what makes the difference. These are supplements, not quick fixes.

Why we built it

The gut runs everything. Most probiotic supplements add good bacteria and stop there. But bacteria without food or a home don't last long. Our Probiotic Chews feed them with prebiotics and support the gut lining they live in – so they arrive, settle in, and get to work. The way they're supposed to.

How we raise the bar

Most probiotics don't make it

The journey from mouth to gut is brutal. For most probiotic strains stomach acid destroys them before they get anywhere near where they need to be. ProbioSEB CSC3™ strains are different. Spore-forming strains built to survive the journey and get to work where it actually matters.

Good bacteria need somewhere to live

Marshmallow Root supports the gut lining that probiotics live in. This creates the right environment for them to thrive, colonize and get to work. The foundation most probiotic formulas overlook.

Two prebiotics to feed every part of the gut

Most supplements use one prebiotic fiber. We use two. FOS ferments quickly, feeding the good bacteria from day one. Inulin works more slowly, reaching further along the colon. More of the gut supported.

The Wuffes Standard™

Scientific principles we obsess over, because every milligram matters.

The right ingredients

5 active ingredients, each with a specific job. ProbioSEB CSC3™, a clinically tested probiotic blend, paired with two prebiotic fibers to feed the good bacteria, Marshmallow Root to support the gut lining they live in, and Pumpkin Powder for digestive fiber.
The right concentrations

4 billion CFU per 2 chews. Formulated at a concentration meaningful enough to actually work. Because spore-forming probiotics that survive the journey are only useful if there are enough of them.
The right blends

Each ingredient targets a specific area, but they work together to achieve the same goal; better gut health.
ProbioSEB CSC3™ provides 4 Billion CFU of spore-forming probiotics per 2 chews. They survive stomach acid and reach the intestines alive, so they can actually get to work. FOS and Inulin feed the good bacteria; FOS for fast fermentation and Inulin for longer-lasting coverage further along the colon. Finally, Marshmallow Root and Pumpkin Powder support the gut lining – where the bacteria live, stay and thrive.

The standards behind every supplement

Certified against the industry's gold standard

The NASC exists because pet supplements deserve the same rigour as the ones you'd take yourself.

We're proud to carry the NASC Quality Seal – awarded only to brands that pass a comprehensive independent audit and maintain ongoing compliance with rigorous quality standards.

It's the clearest signal a dog parent has that what's on the label is what's in the product. It can't be purchased. It has to be earned.

Every formula we make is held to the same three-part standard: The right ingredients, at the right concentrations, in the right blends.

Not because it's the easiest way to make a supplement. But because it's the right way to make one that works.

It's the difference between a product that looks good on a label and one that makes a real difference to your dog.

Every Wuffes formula is independently tested for quality, purity and potency once it leaves our facility.

It's an extra layer of accountability we built into our process – not because we're required to, but because if you're going to give something to your dog every day, it has to be exactly right.

Processing can degrade active ingredients, reducing their potency before the product even reaches your dog.

We test every formula post-manufacturing to verify that what we formulated is what survived. If the active ingredients didn't make it through intact, neither does the product.

Every ingredient in every Wuffes formula is there for a specific, documented reason. No wheat, corn, soy or potato. No unnecessary binders or fillers. No artificial colours or flavourings.

Where flavouring is needed, we use whole food flavours such as pork liver, not synthetic alternatives or derivatives.

Nothing enters the formula without justification. Nothing is there to bulk out the product or reduce cost.

A supplement your dog won't eat is no supplement at all – every dog parent knows that feeling.

The industry's answer to palatability (taste) testing is laboratory dogs. Kept in controlled environments, used specifically for this purpose. We don't think that's the right way to do it, and we never have.

So before any Wuffes formula goes to market, it's tested by real dogs, sourced from our own large community of dog parents. Simply put, if dogs don't like it, it doesn't make the cut.

Supplements take time to work. The active ingredients need time to build up, absorb, and begin working at a cellular level.

You make a commitment to your dog, so here's ours to you. 90 days to try it, stick with it and if you're not happy with the results – we'll make it right.

We're proud that less than 1% of our customers ever need to take us up on it.

Every Wuffes supplement is manufactured in certified facilities in the United States, held to some of the most rigorous production standards in the world.

FDA-registered, cGMP-compliant facilities where every stage of production, from raw material intake to finished product, is documented, audited, and held to a consistent standard.

Our Probiotic Chews are crafted to enhance your dog’s digestive health with a unique blend of probiotics, prebiotics, and soothing ingredients. Clinically tested probiotics (ProbioSEB CSC3™) help maintain a healthy balance of gut bacteria, supporting digestion and strengthening immune health. Prebiotics such as FOS and inulin nourish beneficial bacteria in the gut, promoting their growth. Marshmallow root soothes the digestive tract, making it ideal for dogs with sensitive stomachs, while pumpkin powder provides fiber to regulate bowel movements and ease digestive discomforts.

Key Benefits:

Supports a balanced gut flora for better digestion and immune health
Nourishes beneficial gut bacteria with prebiotics
Soothes and calms the digestive tract for dogs with sensitive stomachs
Provides fiber to regulate bowel movements and alleviate digestive issues
Enhances overall vitality and well-being for dogs of all ages and breeds

Our Probiotic Chews are shelf stable and can be stored in your cupboard at room temperature for up to 3 months. If you intend to use the chews beyond 3 months, we recommend storing your chews in the fridge to preserve their freshness.

In order to look out for as many pups as possible, we formulated our chews with allergies in mind. If your pet is particularly sensitive, please note that our Probiotic Chews include Pork, Fish Oil and Rosemary Extract.

In the event that your dog eats too many all at once (yes, they’re that good), you can expect your dog to have minor issues such as gastrointestinal discomfort, including gas and bloating. These symptoms should subside in 2-3 days. If your dog has persistent vomiting and diarrhea, please consult your veterinarian. Your vet will make recommendations based on your pet’s age, size and any pre-existing conditions.

Our products are proudly made in the USA from globally sourced ingredients.

Probiotics can be a great addition to your dog's routine, especially if you're noticing signs that suggest digestive or immune system concerns. Here are some key indicators that your dog might benefit from a probiotic supplement:

Digestive Disturbances: If your dog frequently experiences diarrhea, constipation, gas, or bloating, it could be a sign of an imbalance in the gut. Probiotics can help restore this balance and support better digestive health.
After Antibiotic Treatment: Antibiotics can disrupt the natural balance of gut bacteria. If your dog has recently been on antibiotics, adding a probiotic can help replenish beneficial bacteria and support recovery.
Dietary Changes: Switching your dog's food can sometimes upset their digestive system. Introducing probiotics during this transition can help maintain digestive stability and prevent gastrointestinal discomfort.
Immune System Support: A healthy gut is closely linked to a strong immune system. Probiotics can enhance your dog's immune response, which is especially beneficial for dogs that are prone to illness or recovering from sickness.
Poor Gut Health : Issues like a dull coat, skin problems, or a general decline in health can sometimes be traced back to the gut. Probiotics may improve overall well-being by enhancing gut health.

If you notice any of these signs in your dog, consider discussing the potential benefits of a probiotic with your veterinarian. They can provide tailored advice based on your dog's specific health needs and conditions.

If your pet consistently struggles with digestive issues or exhibits one or more of the signs and symptoms of discomfort listed above, our Probiotic Chews can help improve their gut health.

Our supplements are built to work together, so you can stack our everyday formulas alongside a balanced diet with no issue. If your dog is already taking another supplement or a prescription medication, talk to your vet before combining.

Our tasty Probiotic Chews can be given to your pet at any time of the day, though we recommend feeding them at mealtimes as it helps increase nutrient absorption.

We’re proud to say that every Wuffes product is made right here in the USA—crafted with care and held to the highest quality standards. We use a mix of domestically and globally sourced ingredients, carefully selected for their safety, effectiveness, and benefits for your pup’s health.

From production to packaging, we’re committed to delivering trustworthy supplements that you (and your dog) can feel good about.

We know your furry friend can't wait to receive their Wuffes, and with all that tail-waggling, all they mean is "Is it here yet?!". Don't worry, we won’t keep you waiting! All orders placed before noon are shipped on the same day, while all other orders will ship within 1 business day.

e.g. If your order is placed on a Friday at 9:00 am, your order will be shipped the same day. If your order is placed on a Friday at 2:00 pm, your order will be shipped until the next Monday.

Where Does Wuffes Ship From?

Wuffes orders ship from the USA. We fulfill orders from three warehouses located in Tracy, CA, Addison, IL, and Atlanta, GA.

More zoomies on the way?

We totally get wanting the best for your mama-to-be! Since our supplements haven’t been tested on pregnant or nursing dogs, we recommend checking with your vet first to make sure it’s the safest choice for her and her pups.

My dog ate the whole tub—what now?

Don’t panic—we know pups can be sneaky snackers! If your dog polished off an entire tub of our Advanced Hip & Joint Support (as long as it's made for their weight), they should be just fine. You might notice some mild symptoms like vomiting, diarrhea, or an upset tummy.

If they got into more than one tub, a tub for a different weight or symptoms last longer than 24 hours, it’s best to check in with your vet just to be safe. And of course, we’re here if you need us!

In the case of our 23-in-1 Multivitamin, certain vitamins (such as Vitamin D3) can cause toxicity in large doses. If you think they’ve eaten too much, it’s always best to be safe and speak to your vet.
