Pug Mama

I have two pugs who eat their expensive dog food IF I mix a little cooked chicken liver with it. However, the liver seems to make their stools runny. It was easy to mix with their food and they didn't seem to notice any difference. The very next day, their poops were firmer and well-formed, and much easier for me to pick up with the bags. So glad to have found something that works so well and so quickly!

Fiber Blend (Oat + Psyllium Husk)

Fiber Blend (Oat + Psyllium Husk)

Our stool support formula is built on a blend of two gentle, natural fibers: Oat Fiber and Psyllium Husk. Psyllium Husk has a long history of use in supporting stool consistency. It absorbs excess water in the gut to help form firmer, healthier stools. Oat Fiber adds gentle bulk and helps keep digestion regular. Together, they give your dog's system what it needs to get back on track after a food switch, travel, or an occasional tummy upset.

Pumpkin Powder

Pumpkin Powder

Pumpkin is one of the most trusted natural go-tos for dog owners when tummies get unsettled. Naturally rich in soluble fiber, pumpkin helps promote digestive comfort and supports healthy stool form. It also brings natural vitamins and antioxidants to the formula, and dogs love the taste, which makes every scoop easy to serve.

Probiotics

Probiotics

Probiotics are beneficial bacteria that help support a healthy balance in your dog's gut microbiome. When routines change, whether through new food, travel, boarding, or a stressful week, that balance can shift, and digestion often shows it first. Daily probiotic support helps keep the gut environment balanced, so your dog stays comfortable through life's everyday changes.

Prebiotics

Prebiotics

Prebiotics are the fuel that beneficial gut bacteria feed on. By nourishing the good bacteria already in your dog's gut, prebiotics help create a balanced environment where healthy digestion can thrive. Paired with probiotics, they work as a team: probiotics add beneficial bacteria, and prebiotics help them flourish.

Flavonoids

Flavonoids

Flavonoids are natural plant compounds found in citrus and other fruits, valued for their antioxidant properties. They help support the body's natural defenses and provide antioxidant support for a healthy gut. Added to our digestive formula, flavonoids help round out complete daily support for your dog's digestive wellness.

Elizabeth C. 5/5 Verified

Cheyenne has had some health issues ranging from teeth infections, chronic ear infections and both bacterial & viral infections, I took her to her vet for her annual checkup the vet advised she needed her teeth cleaned again (she had dental surgery 2 yrs ago) I really did not want her to undergo anesthesia again as took her little longer to be herself again after the surgery and trying to brush her teeth did not go well. I watched a video on U tube 1 day about Pup Labs the video and read all the reviews I was intrigued by what I read since then started giving her K9 belly bliss, Anti Itch spray then tried the dental powder 2 weeks ago her teeth are pearly white, breath doesn't smell and the plaque and tarter are gone, it is easy to sprinkle on her food, I told my family about it advise the products are real and they work, Cheyenne's demeanor has changed since using these products as she is a much happier dog, with everything you hear coming out about what is being used in animal products whether it be food, medication or over the counter products, I am more attentive to what Cheyenne ingest. I will be reordering the dental powder again & if need anything else Pups Lab is my 1st go to "I APPRECIATE THE EXPLANATIONS and VIDEOS IN DETAIL HOW ISSUES START WITH ANIMALS HEALTH" Thank you Carla and Cheyenne

Gabrie S. 5/5 Verified

I have bought so many things for my dog that were a waste of money.i was expecting the same with this product, but I was pleasantly surprised. It does everything it promises! After only 3 weeks of using this powder on m pup she received a 5 (highest rating) from my groomer for her teeth! I am back to buy more (I gave my other extra packets to my brother and dog walker) and am going to try the ear cleaner drops.

My dog does not need to have his teeth cleaned every six months only once a year and the doctors are amazed at how clean his gums and teeth are with us. It’s a miracle. Thank you.

Mary Lou G. 5/5

Dog likes it and it helps her teeth

Jennifer K. 5/5 Verified

Just started her on it

Teona L. 5/5 Verified

The vet showed me where my 4 year old dog had some plaque and gum swelling on a back tooth. I began using the Pro Denta. Her tooth was clean and her gum redness was cleared up within a week! Unbelievable!

Linda W. 5/5 Verified

Hate the website. Love the product.

Nicholas H. 5/5 Verified

I am very happy with the results of the product. We have tried numerous products for our Pups bad breath & teeth. This is the only one that has worked. Do not like the subscription element & auto billing our credit card. I have enough product for the entire year. I had to cancel my subscription to stop it. Totally ridiculous.

Michael S. 5/5 Verified

My two dogs enjoyed this Prodenta product. I mix the Prodenta in their dry food and it is making a difference on their teeth.

Frequently Asked Questions

My Dog's Stomach Gets Upset Every Time We Switch Food or Travel. Will This Help?

+

That's exactly the kind of situation K9 QuickFirm was made for. Food changes, travel, boarding and stressful weeks can all throw off your dog's digestion. QuickFirm combines a fiber blend (Oat and Psyllium Husk), pumpkin, prebiotics and probiotics to help support firm, healthy stools and a balanced gut. For best results, start giving it a few days before a planned food switch or trip and continue daily throughout.

How Soon Will I Notice a Difference?

+

Every dog is different. Some owners notice a change in stool consistency within the first few days, while others see the full benefit after a couple of weeks of daily use. Consistency is key, so we recommend giving QuickFirm every day for at least two weeks before judging results. You're also covered by our 180-day money-back guarantee.

When Should I See a Vet Instead?

+

QuickFirm is designed to support digestive health during occasional and situational tummy troubles. Contact your vet right away if your dog has diarrhea lasting more than 48 hours, blood in the stool, vomiting, lethargy, loss of appetite, or signs of dehydration, or if your dog is a young puppy or senior. These can be signs of something that needs medical attention.

Is It Safe for All Breeds and Ages?

+

Yes. QuickFirm is made with natural ingredients and is suitable for dogs of all sizes and breeds. Simply follow the weight-based serving guide on the bag. It is not recommended for pregnant or nursing dogs. If your dog is a puppy, has a health condition or is on medication, check with your vet before starting any new supplement.

Should I Give It Daily or Only When My Dog Has an Upset Stomach?

+

Both work. Many owners give QuickFirm daily to support ongoing digestive balance, especially for dogs with sensitive stomachs. Others keep a bag on hand and start it during food changes, travel, boarding or whenever tummy troubles pop up. Daily use gives the prebiotics and probiotics the best chance to support a healthy gut over time.

How Long Does One Bag Last, and How Many Should I Get for Two Dogs?

+

Each bag contains 75g. At the recommended serving, one bag lasts about 30 days for a dog under 25 lb, about 20 days for a dog 26 to 50 lb, and about 15 days for a dog over 50 lb. For two dogs, add their daily servings together. For example, two medium dogs will go through a bag in about 10 days, so a multi-pack or subscription is the easiest way to stay stocked.

Can I Mix It With Wet Food? What If My Dog Is a Picky Eater?

+

Yes. QuickFirm mixes easily into wet or dry food. For dry kibble, add a splash of water or broth to help the powder stick. It contains pumpkin, which most dogs enjoy, so even picky eaters usually take to it. If your dog is hesitant, start with a smaller amount and build up to the full serving over a few days.

Where Is K9 QuickFirm Made?

+

K9 QuickFirm is made in the USA in a GMP-certified facility, following strict quality standards for purity and potency. Every ingredient is chosen to deliver gentle, effective digestive support you can feel good about giving your dog.
