“Have been using the drops on the back of the neck, but recently stopped working (tried different brands), Comfortis works! And Allivet has the best price by far.”
“This product is way easier to use than topical medications such as Frontline. I don't have to worry about my dog getting wet or going swimming after right giving her Comfortis. With Frontline, I had to make sure that she stayed dry for couple of days after the medicine was put on.”
“This is the best flea preventative that I have been able to find for my dog. She is allergic to flea bites and since being on Comfortis has had no issues. Allivet also has the best price, fast shipping and ordering could not be easier.”
