I am curious about using Frontline on my dogs. My question is; Is it Waterproof- does it wear off if in water frequently? And another question, are there any harmful affects from using this product. Is there any test results that I could see before using this product?
Yes, frontline is waterproof, just follow the instructions on the box. I do not know of any harmful affects of using frontline and I use it on my dog. You do not need any test prior to use. Thanks, vetcare
