My Pebbles has fleas. I was shocked because my babies never had them. I just thought she had some kind of allergies, so I brought her in to the doctor and he found flea poop in her coat. I freaked. He gave me Capstar Pill for each of my babies and I put the frontline plus on them. I buy the box for the biggest dog possible then I only use .65 ml on each dog. It is the same price as for the small dogs but I only have to use 1 tube on all four of them. It is a big time money saver. I'm dying to give them a bath but I have to wait I think 2 days after I put it on them. I am soooooo freaked out.
