“Best thing we've found for our dogs. This product doesn't do anything strange to them after they take it like the stuff they used to put behind their neck.”
“I have been using Comfortis for the past 2 years with all my pets (cats and dogs) at the lowest dosage. It works great against fleas, and I have seen no negative side effects. Also I have only seen an occasional tick (not attached) although Comfortis is not supposed to be effective against ticks. I really like the product!”
