Bliss

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.

Bliss is the calming chew in the Supplements range. It is formulated for dogs prone to stress and nervousness, including dogs who find separation, loud noises, travel, visitors or new places hard. It combines varied prebiotic fibres and two postbiotics with calming amino acids, three forms of magnesium and calming botanicals to support a settled disposition and resilience to everyday stress, without sedation.

Two ways. Prebiotic fibres from five whole-food sources, fava bean, pea, potato, pumpkin seed and apple, feed a wide range of beneficial gut bacteria, because different bacteria break down different fibres. Two postbiotics, TruPet™ and heat-inactivated Lactobacillus helveticus HA-122, deliver the beneficial compounds those bacteria produce, and because they are not alive they do not need to survive digestion to do their work. Bliss contains no live probiotic, so for the full prebiotic, probiotic and postbiotic foundation, many owners pair Bliss with Biotics.

The gut-brain axis is the two-way communication between the gut and the brain, through the vagus nerve, hormones, the immune system and the compounds gut bacteria produce. Around 90% of the body's serotonin is made in the gut, and the gut microbiome helps shape the stress response. Bliss supports both ends: the gut foundation and the brain chemistry of calm. Read more about the gut-brain axis.

No. Bliss contains no sedatives. It is formulated to support relaxed calm, so your dog stays alert and fully themselves. If you ever notice unusual drowsiness, reduce to a half dose, build up gradually and check with your vet.

Bliss supports calm through everyday stressors and known events. For fireworks season or a planned journey, many owners start daily use several weeks ahead and give that day's amount two to three hours before the event. Bliss is not a sedative and works best alongside a safe space, calm handling and, where needed, advice from a behaviourist.

Bliss is a food supplement, not a veterinary medicine, and it is not a treatment for any behaviour condition. Many owners of dogs with a diagnosed condition give Bliss daily to support calm alongside the plan their vet or behaviourist 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.

Durelax® combines magnesium salts (sulphate and oxide) with lemon balm extract (Melissa officinalis) on a sepiolite clay carrier. Together with magnesium glycinate, it gives Bliss three forms of magnesium, a mineral involved in nerve signalling, and lemon balm has been studied for its calming effect in dogs.

No. Bliss 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 calm is your main concern, Bliss is the place to start. You can compare all seven Bites on our Supplements page.

Supplements are made without meat, wheat, soy, corn or artificial additives, which suits many dogs with sensitivities. They are formulated for dogs from 12 weeks and older. If your dog has a medical condition or takes medication, check with your vet before starting.

Bliss 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 Bliss gentle on sensitive dogs. It suits vegan households too, but the reason we make it this way is health, not ideology.

For pregnant or nursing dogs, check with your vet before starting. Their nutritional needs change during this time, and your vet can advise on what is right for them.

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.

Bliss is well tolerated by most dogs. A few have a minor digestive adjustment in the first few days as the microbiome adapts. If your dog seems unusually drowsy at the usual amount, reduce to a half dose, build up gradually and check with your vet.

Bliss 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, not a token pinch. Bliss is nutritionist formulated and vet approved, and 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 amino acids and delicate oils to vitamins and plant compounds. Keeping the process gentle helps preserve them, so the levels shown in the formula are protected through manufacture.

Some owners notice a calmer dog within the first days. The deeper changes, a more relaxed baseline and quicker recovery from stressful moments, build over four to eight weeks of consistent daily use as the gut-brain and stress-response support establish. Giving Bliss consistently each day matters more than giving more.

Bliss is a food supplement rather than a medicine, and it generally sits comfortably alongside a balanced diet and other supplements. If your dog takes medication, including anti-anxiety or behaviour medication, check with your vet first, as they can advise on timing and suitability.

Give Bliss 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.

Bliss is made from food-grade ingredients at gentle levels, so an extra Bite now and then is not a cause for alarm. Stick to the daily amount for your dog's weight for the best results. If your dog ever gets into a whole pack, a large one-off amount may cause temporary loose stools or drowsiness, so keep an eye on them and contact your vet if you have any concerns.

Yes. Many owners pair Bliss with Biotics as the Calming Routine: Biotics adds a live probiotic and branded prebiotics to complete the gut foundation beneath Bliss. 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.
