Seven Bites. One Gut-First Foundation.

Every scientifically formulated Bite is built on a gut-health foundation, then layered with targeted bioactives for your dog's specific issue.

Free from common allergens: chicken, beef, wheat, corn and soy. Most probiotic chews are made with the very proteins sensitive dogs react to. Ours are not.

  • Scientifically formulated
  • Active doses that count

How It Works

How Each Bite Works

Most gut nutrition stops at one pillar, a prebiotic or a probiotic. Bonza is built on all three: prebiotics that feed, probiotics that produce, and postbiotics that deliver.

  1. Nourish the Gut

    Every Bite begins with gut-supporting compounds: prebiotics, probiotics and postbiotics that support your dog's microbial diversity, support their gut barrier and help maintain a balanced microbiome.

    Prebiotics · Probiotics · Postbiotics

  2. Activate the Pathway

    Targeted bioactives then work along a specific gut-organ axis, delivering phytonutrients, adaptogens and soothing botanicals where they are needed to best support your dog's issue.

  3. See the Difference

    As their gut health improves, owners notice calmer behaviour, healthier skin, easier movement and steadier digestion.

    Many owners notice changes over the first few weeks

The shared foundation

Every Bite Begins with the Biotics Triad

Prebiotics feed the good bacteria, probiotics add more of them, and postbiotics deliver the beneficial compounds they produce.

The same three-part foundation behind every Bite, and behind our complete food.

the connected system

Complete Nutrition. Targeted Support.

The gut communicates with every major system in your dog's body, so each Bite is built to work through the gut, not around it.

That is why we suggest starting with Biotics. Support a balanced microbiome first, and every targeted Bite that follows works from a stronger foundation. Care for the gut, and you care for the whole dog. That is what we mean by One Gut. Whole Dog.™

FAQ

Your Questions Answered

What are Bonza Supplements?

Supplements take Bonza’s approach to canine nutrition further: rather than everyday nutrition alone, they deliver a higher concentration of targeted, powerful nutrients to support your dog’s optimal health and wellbeing. Bites are their own product, with a renewal schedule based on your dog’s size rather than your regular food subscription.

What is the Biotics Triad?

The Biotics Triad is the combination at the heart of Biotics: prebiotics, a probiotic and postbiotics working together to support a balanced gut microbiome. Prebiotics feed the good bacteria, a probiotic adds more of them, and postbiotics deliver the beneficial compounds they produce. Biotics brings the full Triad together with targeted bioactives, including L-Glutamine, zinc and botanicals, to support microbial balance, the gut lining and a healthy, well-regulated immune response.

What are the gut-organ axes?

Your dog’s gut microbiome doesn’t only manage digestion: it communicates with the brain, heart, joints, skin, liver, immune system and metabolic pathways through what scientists call gut-organ axes. When the gut is healthy, these communication pathways can work as they should, supporting everything from mood and mobility to skin condition and immune resilience. Bonza formulates every Bite to support the gut first, and Boost, our whole-body formula, is designed to support all 8 gut-organ axes in one daily chew.

Which Bioactive Bite is right for my dog?

Each Bite is formulated around a focus, so the right one depends on what matters most for your dog. Boost is the whole-body daily foundation, Biotics supports gut microbiome balance and immune health, Belly supports digestive comfort and healthy stools, Bounce supports joint comfort and healthy movement, Block supports skin comfort and coat condition, Bliss supports calmer behaviour and stress resilience, and Banish helps repel fleas and ticks alongside the parasite control your vet recommends. Not sure? Reach out to our team via phone, email or chat and we’ll help you choose.

How long until I see a difference?

Every dog is different, and Bites build with consistent daily use. Many owners notice changes in energy, digestive comfort or ease of movement within two to four weeks, while benefits for skin and coat, joints and immune resilience build cumulatively over six to twelve weeks. Calming support typically builds over four to eight weeks, and dogs with long-standing sensitivities may take longer. Stick to the daily amount for your dog’s weight for the best results.

Are Supplements suitable for sensitive dogs, puppies and seniors?

Bonza’s plant-based recipes are formulated to meet and exceed adult dog nutritional requirements, and many owners of puppies and allergy-sensitive dogs already feed Bonza successfully. We’d still recommend checking with your vet before introducing any new food, including Bites, to a puppy or senior dog. If your dog has allergies or sensitivities, Bonza’s hypoallergenic, vegan formulation was designed with exactly that in mind.

Are Supplements safe?

Safety is our top priority. Bonza is made by manufacturing partners who meet the requirements of the IFS Food Version 7 certification, one of the most rigorous food-safety standards in the industry, and every recipe is produced to that same standard.

Can I give my dog more than one Bite at a time?

Bites are formulated for different areas of your dog’s health, and some pair well: Boost pairs with Bounce for seniors with specific joint or mobility concerns, and many owners pair Bliss with Biotics for the full prebiotic, probiotic and postbiotic foundation. Each Bite has its own daily amount based on your dog’s weight, so follow the guidance on each product page. If your dog is on a veterinary-prescribed diet, or is pregnant or nursing, check with your vet first. Our team is always happy to help you build the right combination.

Can I give Bites alongside my dog's usual food?

Bites are a separate product to your regular Bonza food subscription, with their own renewal schedule based on your dog’s size rather than the feed plan calculated for their everyday meals. That means Bites don’t automatically bundle into your existing subscription, but if you’d like them added to your regular delivery anyway, just let us know and we can arrange it.

What if my dog doesn't like the Supplements?

Some dogs are naturally cautious about new foods, a reluctance called food neophobia, so we recommend introducing anything new, including Bites, gradually over about 8 days (up to 10-12 days for fussier eaters). If your dog still isn’t enjoying them after that transition, we’re committed to making it right: get in touch by phone, email or chat and we’ll happily refund you.

What is the Health & Happiness Guarantee?

Your dog’s health, and their happiness at mealtimes, is our No. 1 priority. We are totally committed to this, so our guarantee is simple and straightforward. Like us, some dogs suffer from food neophobia (a fancy term for a reluctance to try new foods), which is why we recommend transitioning your dog to any new food (not just ours) gradually over an 8-day period. This is the length of time scientists and canine nutritionists expect it will take for your dog to get used to the change in smell, texture and flavour of any new food even if they are reluctant initially. This process can take up to 10-12 days for fussier dogs. If they are not licking their bowl clean after their transition (and giving you those “More please” eyes), you must restore their mealtime happiness and we are committed to making sure this happens for their best life. Please contact us via phone, email or chat and we’ll happily get your money back to you.

How do I give them, and how does Subscribe & Save work?

Like our full-size food, Bites can be added to a Bonza subscription: tell us a little about your dog and we’ll calculate a personalised delivery schedule so a fresh box arrives right when you need it. You’re always in control, pause, reschedule or cancel anytime from your account dashboard, and subscribing saves you 10% for the lifetime of the subscription with free delivery included.

How should I store them?

Keep Bites in their original pack, closed securely after every use, in a cool, dry place away from direct sunlight and heat. Store them out of reach of children and pets, and use them before the date printed on the pack. If you have any questions about storing your Bites, reach out to our team via phone, email or chat.
