I have four dogs and all big boys were badly infested with fleas. After starting with this treatment, we never found a flea problem.

Had a dog with lots of fleas. This product got rid of them. The 60 lb bulldog is now flea free.

Best treatment for our dog's flea protection

we are away on vacation and this corono crisis, hope this helps our dog best

Used K9 Advantix on my pregnant dog and it was really safe.
