Hi T..I personally will not use an oral flea or tick preventative. Why circulate a flea product internally through the dog to get it to the skin level? I can not imagine it doesnt effect the organs. If I would not swallow pesticide myself to kill and repel mosquitos or ticks why should my dog? One of my boarders had a horrible reaction to their glea/tick collar. Not sure which brand but it was one of the two mentioned above.
