Banish

Supplements are daily soft-chew supplements for dogs. Every Bite is built on a gut-health foundation of named biotics, then layered with targeted bioactives that work along a specific gut-organ axis to support a particular concern, from digestion and skin to calm, joints and senior vitality.

Banish is the flea and tick season chew in the Supplements range. It is formulated for dogs whose skin and coat face the outdoors every day, and for owners who want natural, daily support through flea and tick season, alongside their usual parasite control. It supports a healthy skin barrier, a glossy coat and your dog's natural defences. It combines prebiotic chicory root and brewers' yeast with a postbiotic, skin-nourishing oils and a botanical blend led by rosemary.

Banish works in three ways, given daily alongside your usual parasite control. It balances the gut with chicory root FOS, brewers' yeast and whole-food fibres, alongside heat-inactivated Lactobacillus helveticus HA-122, because a balanced gut supports a balanced skin microbiome. It nourishes the skin and coat with hemp seed oil, DHAgold™ algae, coconut oil, B vitamins and natural vitamin E. And it supports your dog's natural defences with brewers' yeast, rosemary, clove leaf, lavender and thyme, ingredients traditionally used to help make dogs less appealing to fleas and ticks, plus lemon balm and antioxidant cranberry, cinnamon and pineapple.

The gut-skin axis is the link between the gut microbiome and the skin. The skin has its own microbiome, and research shows that when gut microbial balance and diversity fall, skin balance can follow. A well-nourished skin barrier also depends on the fats, vitamins and antioxidants that reach it from within. That is why Banish supports the gut and the skin together.

No. Banish is a food supplement, not a veterinary medicine, and it is not a substitute for licensed flea, tick or worming treatments. It contains ingredients traditionally used to help make dogs less appealing to fleas and ticks, and supports skin, coat and natural defences through the season. Give it alongside the parasite control your vet recommends.

Many owners start Banish in early spring, around February or March, before flea and tick season gets going, and continue through to the autumn. Others give it year-round. Either way, give it every day: it works as part of a consistent daily routine, not as a one-off.

Banish is a food supplement, not a veterinary medicine, and it is not a treatment for any skin condition. Many owners of dogs with a diagnosed skin condition give Banish daily to support skin and coat alongside the plan their vet has put in place. Talk to your vet before starting, particularly if your dog takes medication, and never stop or change a prescribed treatment without their advice.

Banish contains very small amounts of clove leaf, lavender and garlic oils, 3mg of each per chew, alongside rosemary, thyme tincture and lemon balm. They are part of the botanical blend traditionally used to help make dogs less appealing to fleas and ticks, and are delivered within a food, at levels set by your dog's weight. Never give essential oils to your dog directly, on their own or undiluted.

Garlic can be harmful to dogs in larger amounts, which is why Banish contains only a very small amount of garlic oil, 3mg per chew, with the daily amount set by your dog's weight. If your dog has anaemia or another blood condition, or takes medication, check with your vet before starting.

No. Banish contains hemp seed oil, pressed from the seeds, which is CBD-free. It is there for its Omega-3 and Omega-6 essential fatty acids, alongside the DHA from DHAgold™ algae.

Choose by the concern that matters most: Belly for digestion, Biotics for microbiome balance, Block for skin and coat, Bliss for calm, Bounce for joints and mobility, Banish for flea-season skin and coat support, and Boost for the senior years. If your dog's skin sensitivities are the main concern, Block is the place to start; for natural support through flea and tick season, choose Banish. You can compare all seven Bites on our Supplements page.

Banish is made without meat, wheat, soy or corn, so it contains no chicken or beef, the proteins most often behind food sensitivities in dogs. That makes it a gentle daily choice for many sensitive dogs. If your dog has a diagnosed allergy, check the full ingredient list above before starting, and have a word with your vet if you are unsure.

Plant-based by consequence, not by trend. The most common food sensitivities in dogs are animal proteins like chicken and beef, so a plant-based formula sidesteps them, which is what makes Banish gentle on sensitive dogs. It suits vegan households too, but the reason we make it this way is health, not ideology.

Banish is formulated for dogs from 12 weeks and older, including seniors. For pregnant or nursing dogs, check with your vet before starting, as Banish contains botanicals and essential oils and their needs change during this time.

Yes. Supplements are food supplements made from food-grade ingredients at gentle, effective levels, formulated by our nutritionist and approved by our veterinary advisory board. They are supplements, not medicines, and are designed to complement a balanced diet rather than replace veterinary care. They are made for daily, long-term use, with no need to cycle on and off. If your dog has a health condition or takes medication, check with your vet before starting.

Banish is well tolerated by most dogs. A few have a minor digestive adjustment in the first few days as the microbiome adapts to the prebiotic fibres, which usually passes within a week. If you notice any change that concerns you, stop giving Banish and speak to your vet.

Banish was formulated by Bonza's founder, Glendon Lloyd, who holds Diplomas in Canine Nutrition and Dog Nutrigenomics, both with Distinction, and it is approved by our Veterinary Advisory Board. Every ingredient is selected on published research and included at a meaningful level.

Yes. Every active is chosen for a reason and included at a meaningful level. For the oils, B vitamins and biotics there are feeding studies in dogs; for several botanicals the evidence is laboratory research on microbes taken from dogs, and we say so. You can see each ingredient, its inclusion level and the published research behind it in the full formula above.

Cold extrusion is a low-temperature way of shaping the chews. Every Bite is formed at just 38°C, close to a dog's body temperature, rather than the high heat of conventional cooking and standard extrusion. That matters because heat degrades many of the actives we use, from prebiotic fibres and delicate oils to vitamins and the volatile compounds in botanicals. Keeping the process gentle helps preserve them, so the levels shown in the formula are protected through manufacture.

Skin renews itself over several weeks and coat grows gradually, so most owners first notice a softer coat after about a month of daily use, with fuller benefits over two to three months. Giving Banish consistently each day matters more than giving more.

Banish is a food supplement rather than a medicine, and it generally sits comfortably alongside a balanced diet, other supplements and the parasite control your vet recommends. If your dog takes medication, check with your vet first, as they can advise on timing and suitability.

Give Banish daily by your dog's weight: one Bite up to 10kg, two Bites for 10 to 20kg, three Bites for 20 to 30kg, and four Bites over 30kg. Give as a treat or with food, and keep to the same time each day. Consistency matters more than giving more.

Stick to the daily amount for your dog's weight. An extra Bite now and then is not a cause for alarm, but if your dog ever gets into a whole pack, contact your vet, as Banish contains botanicals and essential oils intended for the daily amount only.

Yes. Many owners give Banish alongside Biotics, which adds a live probiotic and further postbiotics to complete the gut foundation beneath it, or alongside the Foundation Routine. For dogs with skin sensitivities, Banish can also be paired with Block. When combining more than one, introduce them gradually and follow the feeding guide on each pack by your dog's weight.

Yes. Supplements are a daily soft chew given as a treat or with food, so they fit alongside whatever your dog already eats, including our Superfoods & Ancient Grains. If you are introducing more than one Bite, add them gradually.
