Whilst this product is waterproof, bathing and swimming should be avoided where possible. If your pet needs a bath, it's recommended you wash your dog before applying Advantix or 2+ weeks after application.

    "I have not had any problems with Pet Drugs Online. They are very prompt with their delivery. My last order with them I had trouble with my prescription from the vet due to wrong date on it, but Pet Drugs Online were very helpful and delivered my dogs medication extremely fast once I got prescription sorted with my vet."
