I really need some advice on using a good flea medicine, I was using frontline on Gracie for the past year, but I noticed the last time I gave it to her she was spinning in circles and acting oddly. She seemed totally out of it for the rest of the day. I thought she was having a seizure when I applied it on her. I would like to get a new flea medicine for her because i really didn't like the way frontline made her feel. Anybody else have this same reaction and is any other recommedations. Thanks
Gracie
