I noticed that my little terrier gets red skin at the application site and then itches other areas until they are red and sore. Anyone else have experience like this. Barnsley also started itching under his front leg and it looks reddened but he doesn't have redness at the application site so I am thinking it was a coincidence. Lilly has sensitive skin and I am wondering if the frontline hasn't been a culprit in the past. I recently clipped her so it was more evident. Before I may have been missing this but she did seem to be scratching more around the time of application. ???
