Thank you both. I finnlly found the "search" feature here and have been searching all the previous threads too. I'm not sure she needs it or not. I called the vet again and they said they did not check for ear mites but will when I bring her in to get her stiches out in ten days. She asked if I saw any fleas on her but I really didn't look real close as she just had surgery and I was hoping she would rest and get used to us. I'm glad you mentioned not to use the supermarket Hartz stuff - I didn't know it was dangerous. I'll look into Advantage or Front line. Debbie
