Many pet owners know this feeling: the dog scratches constantly, is restless, can't settle down – and you don't know how to really help. Chemical protection products often work, but leave residue on the skin, can cause irritation, and put long-term strain on the animal's system. This is exactly where BiteBlock® comes in. The naturally developed tag continuously releases a fine scent cloud of highly concentrated essential oils. These confuse the scent detection system of fleas, ticks and parasites – making your dog invisible to them. Instead of aggressive chemicals, the patented SmartRelease Technology™ ensures an even, controlled release of active ingredients over a full 12 months – reliable, gentle and without side effects. Experience shows that simply attaching it to the collar makes a noticeable difference – on walks, in the garden and in everyday life. BiteBlock® was developed to give your pet real protection – natural, waterproof and suitable for every dog. Not an ordinary protection product. But a well-thought-out solution for pet owners who want the best for their dog – without compromise. BiteBlock® – because your pet should be protected every day.

Vomiting. Tremors. Lethargy. Seizures. More vets are seeing these reactions after chemical treatments than most owners realize. Some health authorities are even looking into possible neurological effects.
The BiteBlock® tag works differently, nothing enters the bloodstream, no monthly pill, no side effects to watch for. Just clip it on the collar, and your dog is covered for 12 months.
Most chemical treatments only start working after the bite. The parasite has to bite first, the active ingredient enters the bloodstream, and only then does it respond. By then, transmission may have already happened.
BiteBlock® works the other way around. Your dog's own body heat slowly releases the natural oils, keeping parasites at a distance before they ever get close.
No chemicals in the blood. No pills. No risk.
Yes. We're confident in our tag and offer a 60-day money-back guarantee. Test it completely risk-free in everyday life. If you're not satisfied, we'll refund the purchase price – no questions asked, no hassle.
For all dog breeds and sizes – thanks to the universal attachment system, it fits any collar. Suitable from 8 weeks of age. For pregnant or nursing female dogs, we recommend consulting a veterinarian beforehand.
Many pet owners report a noticeable change after just a few days. What matters is that the tag is worn continuously on the collar – this is how the natural active ingredients develop their full protective effect.
Yes. The tag is completely waterproof. Thanks to SmartRelease Technology™, the active ingredients remain fully intact even while swimming, in rain, and in any weather.
No. BiteBlock® uses only 100% natural essential oils – peppermint oil, chamomile oil and citronella oil. No pesticides, no synthetic active ingredients, no side effects.
