It can be, but only in excessively large quantities. Garlic is part of the Allium family (like onions and leeks), which can be harmful in high doses. But to reach a toxic level, a medium-sized dog would need to eat 60–120 cloves in one go.

D33 contains less than 1/1000th of that - a completely safe level, garlic has been shown to support the immune system, act as a natural antibacterial, and even help keep fleas and ticks at bay.

It’s all about the dose. We use only what’s safe and what works.

There’s a lot of online noise about kale and kidney stones in dogs but here’s the truth: the concern comes from high levels of oxalates, which are only an issue in large, raw servings.

At the small, balanced amount we use in D33, kale is not just safe, it’s useful. It’s rich in antioxidants and supports everything from cellular function to skin and coat health.

Like any great ingredient, it’s not about if dogs can have it, it’s how much, and how it fits into the bigger picture.

You might hear talk about flax containing phytoestrogens or natural compounds that sound scary.

But ground flaxseed in moderate amounts is one of the best sources of Omega-3s and fibre. It’s great for skin and digestion and totally safe at the 165mg per scoop we use.

A powerhouse ingredient with a caveat: low-quality spirulina can be contaminated. That’s why we source high-quality, lab-tested spirulina only.

It’s brilliant for detox, energy, and immune support, as well as being totally safe at 120mg per scoop.

Yes, and not just safely, but beneficially. The confusion usually comes from wild mushrooms, which can absolutely be toxic. But the functional mushrooms we use; Reishi, Cordyceps, and Lion’s Mane are cultivated, researched, and well-studied.

We’re not throwing in trendy extracts. These are whole food mushroom powders, included in proper doses to support cognition, stress response, immunity, and long-term health.

Reishi – Known as the “mushroom of immortality,” used for immune balance and calming.

Cordyceps – Supports energy, endurance, and cellular health.

Lion’s Mane – Studied for its role in brain health and focus.

No magic, no mystery, just functional fungi your dog’s body actually knows what to do with.

Hemp seeds are completely safe, natural, and incredibly nutritious. They contain no THC and does not alter your dog’s behaviour. Just cold-pressed, whole hemp seed is a rich source of omega fatty acids, protein, and minerals.

It’s one of nature’s best skin-and-coat boosters, supports joints, and adds healthy fats to your dog’s diet, all in a form that’s easy to absorb.

No buzz, no controversy. Just a functional seed your dog will actually benefit from.
