I swear Dakota and Zoey are water proof it rolled off them. I applied to the back of their neck on the skin and it seem to come up through their fur. I had tp seperate them fearing one would try to lick it off the other.
You need to apply it in more than one spot. You can apply Advantix in several spots along the spine -- first one between the shoulder blades, moving down until you hit the base of the tail. The easiest way I have found to do it is to take a comb and literally part the hair so that I am applying to the skin. I do this in about 5 spots.
Yep, just put Sammi's on this afternoon. I put it in 4 differant spots, does leave a little grease mark, but that goes away in a day or two. Remember to keep them out of the water for a couple of days.
