Frontline Reaction? I put Frontline on my Coco (7lbs) and then put a shirt on her so my toddler wouldn't touch the medicine. Coco was running around like something was bothering her, I assumed it was the shirt. The next day I saw traces of blood in her hair in the same area I applied the Frontline. Has anyone had a reaction like this? I didn't even use the full amount. |
