How does Bug-K9 Max Strength support my dog’s natural defences against pests?
+Bug-K9 Max Strength is a natural supplement designed to support your dog’s internal shield against biting pests like fleas, ticks, and mites, without toxins or potentially unsafe chemicals.
Here’s how it works:
Botanical Powerhouse Blend
Bug-K9 includes a potent mix of natural herbs and spices, like black cumin seed, pumpkin seed, ginger, fennel, cinnamon, fenugreek, and peppermint, which may help create a less appealing scent and taste profile for pests from the inside out.
Gut Support with Probiotics & Prebiotics
A healthy gut = a stronger immune system. With ingredients like chicory inulin (a prebiotic) and Enterococcus Faecium (a probiotic), Bug-K9 helps your dog maintain strong internal defences.
Zinc & Selenium
These trace elements support immune function and skin health, both of which are key in resisting irritation and infection from bites.
Vitamin A
Supports healthy skin and coat, which provides a stronger physical barrier against pests and environmental irritation..
What to Expect:
A stronger immune response
Healthier skin and coat
A less attractive host for pests
A gentler, more natural approach to pest resistance

How do I give this supplement to my dog?
+We've produced Bug-K9 Max Strength as a powder supplement, making it easy to add to your dog's daily food. Measure and mix! We love to spread ours on K9-Calm Mats for an extra enriching boost.
How do I know if I can ditch the pesticide treatments for my dog, or if a multi-pronged attack is needed?
+Additional measures may be needed in some regions with a high prevalence of pests. Bug-K9 Max Strength can complement your dog’s routine for optimal wellness.
A multi-prong approach, utilising the Bug-K9 Defence Kit, can give your dog the extra protection they need, and you peace of mind.
However, it’s important to know this is not the case everywhere. In most geographical locations, this is NOT necessary, so knowing your area, your dog, and your lifestyle is key.
Is this dog supplement suitable for all breeds, ages and sizes of dog?
+Yes! The only thing that affects the daily dosage of Bug-K9 Max Strength is your dog’s size. See our feeding info chart for more details.
Can I feed Bug-K9 Max Strength to my dog when on prescription medication?
+Because the ingredients in our supplements are all-natural and have been formulated by vets and nutritionists, they can usually be used in conjunction with prescription medication. We would always recommend that you consult with your vet before changing your dog’s diet if your dog is on prescription medication.
My dog is on a special diet. Can they still have this?
+Yes! This works with any diet. The formula is gluten-free and is designed to assist your dog’s gut, not upset it!

100mg
These superpower seeds contain cucurbitin, which acts as a natural dewormer that leaves intestinal parasites paralysed and unable to reproduce.

60mg
Cassia cinnamon’s bark contains high levels of cinnamaldehyde, giving it its distinctive aroma and providing natural antimicrobial properties that work with ginger to help reduce Giardia infections.

100mg
Used for centuries as a traditional remedy against all stages of intestinal parasites, these mighty seeds back up your dog’s immune system to combat worms.

60mg
Fennel is rich in key nutrients and essential oils—especially anethole—which provides natural antimicrobial and anti-parasitic support while giving the herb its distinctive anise flavour.

60mg
Ginger’s rhizome and root contain potent active compounds that provide wide-ranging benefits—including anti-inflammatory, antimicrobial, and natural anti-parasitic effects—with early research showing promising anthelmintic action in reducing parasite egg counts.

60mg
Peppermint (Mentha x piperita) helps soothe the digestive system, with studies showing its extracts can inhibit the growth and attachment of Giardia lamblia, the parasite responsible for giardiasis.

Vitamin A supports a healthy intestinal barrier, and studies show that higher levels of Vitamin A—especially when combined with zinc—significantly reduce the incidence of parasitic infections like giardia.
