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 dog diarrhea supplement contains a blend of two gentle, natural fibers, Oat Fiber and Psyllium Husk. Psyllium Husk has long been used to help regulate stool consistency. It soaks up extra water in the intestines, which helps make firmer, healthier stools. Oat Fiber provides soft fiber and promotes proper digestion. These two natural fibers work together to help your dog's digestive system after a change in diet, travel, or an occasional upset stomach.

Pumpkin Powder

Pumpkin Powder

Pumpkin is one of the most trusted natural go-tos for dogs with tummy troubles. It’s rich in soluble fiber, which aids digestion and healthy bowel movements. Pumpkin also adds vitamins and antioxidants to the formula, and dogs also enjoy the taste, making it easy to serve every scoop.

Probiotics

Probiotics

Probiotics are beneficial bacteria that help maintain a healthy balance in your dog’s gut microbiome. When routines change, such as introducing new food, traveling, boarding, or a stressful week, the healthy balance can shift, and unsettled tummies and diarrhea are often the first signs. Daily probiotic supplementation helps maintain the balance, making your dog comfortable through life’s everyday changes. Check our dog probiotics for other digestive-support supplements.

Prebiotics

Prebiotics

Prebiotics provide food for beneficial bacteria in the dog’s stomach, ensuring their growth and proliferation. On the other hand, probiotics introduce additional beneficial bacteria into the digestive system. Together, they help maintain a healthy balance in your dog’s digestive system. Our dog diarrhea supplement includes prebiotics and probiotics to provide maximum support for your dog’s stomach.

Flavonoids

Flavonoids

Flavonoids are natural antioxidants found in citrus and other fruits. They help support the body's natural defenses and provide antioxidant support for a healthy gut. We’ve added flavonoids to our anti-diarrhea supplement for dogs to help round out complete daily support for your dog's digestive wellness.

Ellie was having constant diarrhea. This morning she had a normal bowel movement. It was formed and it was such a relief to her and to me. Thank you.

She is better, and things are easy to clean up. Anna Gott

Frequently Asked Questions

Will QuickFirm Help When My Dog's Stomach Gets Upset During Travel or a Food Change?

+

K9 QuickFirm is specifically formulated for use when your dog gets a digestive upset due to changes in food, traveling, boarding, and stressful times. It contains oat and psyllium fiber, pumpkin, prebiotics, and probiotics that support a well-balanced gut microbiome and firm stools. We recommend starting several days before a planned trip or diet change and continuing daily.

How Quickly Does This Anti-Diarrhea Supplement for Dogs Work?

+

This differs greatly from dog to dog. Some dogs show a change in stool consistency within the first few days, while others may take a couple of weeks of daily use to see the full benefit. However, for the best results, we suggest using it continuously for at least two weeks.

When Should I Take My Dog to a Vet for Diarrhea?

+

If your pet has diarrhea that doesn’t go away in 48 hours, or has bloody stool, vomiting, lethargy, poor appetite, or signs of dehydration, contact your vet as soon as possible. Also, young puppies and old dogs experiencing diarrhea should visit a vet. K9 QuickFirm supports your dog's digestion during digestive disturbances only.

Is QuickFirm Safe for All Dog Breeds and Ages?

+

QuickFirm is suitable for dogs of all sizes and breeds when given according to its weight-based serving guide. Don’t give it to pregnant or nursing dogs. If your dog is a puppy, has an existing health condition, or takes medication, speak to your veterinarian before introducing a new supplement.

Can I Use K9 QuickFirm Every Day?

+

It’s safe to give K9 QuickFirm daily to support digestion, or use it when your dog has digestive upset during changes like travel, boarding, or new foods. We recommend using it daily to provide consistent prebiotic and probiotic support for the gut microbiome.

How Long Does One Bag Last?

+

Each K9 QuickFirm bag contains 75g. At the recommended serving, one bag lasts around 30 days for a dog under 25 lbs, 20 days for a dog weighing 26-50 lbs, and 15 days for a dog over 50 lbs. For two dogs, combine their daily serving requirements to work out how quickly you'll use each bag. Two medium dogs, for example, will use approximately one bag every 10 days.

Where Is K9 QuickFirm Made?

+

K9 QuickFirm is manufactured in a GMP-compliant facility in the USA. We carefully selected the ingredients in K9 QuickFirm to provide gentle digestive support and firm, healthy stools. The result is an easy-to-use daily powder for pet parents looking for anti-diarrhea supplements for dogs.
