BoulK9 Saccharomyces Boulardii Probiotic for Dogs and Cats, 10 Caps

About BoulK9

Diarrhoea is one of the most common reasons dogs and cats need a vet. Antibiotics, a change of food, stress and gut infections can all upset the balance of gut bacteria.

BoulK9 is a capsule from Stanford that contains Saccharomyces boulardii (CNCM I-1079) 5 billion CFU (250 mg) per capsule. Saccharomyces boulardii is a probiotic yeast.

It is used for diarrhoea, loose stools, antibiotic-associated diarrhoea and long-term gut support. Ask your vet whether it suits your pet, especially if your pet has a health condition or takes other medicines.

Each capsule contains Saccharomyces boulardii strain CNCM I-1079 at 5 billion CFU (250 mg). This is a probiotic yeast, not a bacterium, so antibiotics do not kill it.

That is why vets often give it alongside a course of antibiotics, to help prevent the loose stools antibiotics can cause.

Studies in dogs have looked at Saccharomyces boulardii for acute and chronic diarrhoea and for gut support. It is used as part of a vet's plan, not as a replacement for finding the cause.

Diarrhoea has many causes, from a sudden change of food to worms, infections and food allergies. Your vet may suggest a stool test, deworming or a bland diet alongside the probiotic.

While your pet recovers, offer small, frequent meals of a gentle diet and make sure fresh water is always available, as diarrhoea causes fluid loss.

Key Ingredients

Active ingredients listed for this product.

Features and Benefits

• Capsule form. A measured dose in each capsule.

How It Works

• Saccharomyces boulardii (CNCM I-1079). It survives stomach acid, competes with harmful microbes, binds some bacterial toxins and supports the gut lining.

How to Use

• Dose. The usual dose is 1 capsule per 5kg body weight a day for dogs, puppies, cats and kittens, or as your vet advises.
• Giving a capsule. Place it at the back of the tongue, close the mouth gently and stroke the throat until your pet swallows. Offer water afterwards.
• With antibiotics. It can be given at the same time as antibiotics, because antibiotics do not kill the yeast.
• Opening the capsule. For small pets, you can open the capsule and mix the powder into a little cool food.
• Storage. Store in a cool, dry place away from direct sunlight, unless the pack gives other storage directions. Keep out of reach of children.

Safety and Precautions

• See your vet straight away if diarrhoea has blood in it, lasts more than 2 days, or comes with vomiting, weakness or a poor appetite.
• Pets with a very weak immune system or a central line should use it only on a vet's advice.
• Tell your vet about any other medicines your pet takes, and if your pet is pregnant, nursing or has liver or kidney problems.

What is BoulK9 used for?

BoulK9 is a probiotic for dogs and cats with diarrhoea, loose stools or an upset gut. Vets also use it during antibiotic courses to help keep stools normal.
