Kills and repels through contact — no biting required.
Fleas, ticks and mosquitoes want to bite your dog. These bites can cause pain, discomfort and possibly deadly disease.
- Tick bites can transmit Lyme disease and Rocky Mountain spotted fever.
- Flea bites can cause flea allergy dermatitis (FAD), an allergic reaction that can cause scratching, hair loss and rashes. If swallowed, an infected flea can also transmit tapeworms.
- Mosquito bites can transmit deadly diseases like heartworm* and West Nile virus.
But let’s be honest — simply avoiding parasites isn’t possible. That’s where K9 Advantix® II for dogs comes in. K9 Advantix® II is a monthly topical treatment that protects your dog by killing and repelling fleas, ticks and mosquitoes.
