BIG mentioned Frontline in answer to a post and I wanted to give results we have had as well as ask for an opinion. Tuesday I treated two of my dogs with Frontline and have had WONDERFUL results. Usually, my little one, Baby, can get a bath at night, the next day she is covered. Literally. She has not had the first flea since her treatment. I have since treated my big dog and am attacking my cat tomorrow. It does state that it is safe for puppies and kittens 8 weeks and older. While I was at the vet's office, she called the company to ask if it was safe for ferrets. The girl who answered said she had ferrets and used it on them with good results and no problems. She applied it with a syringe on their backs and rubbed it in. However, I am a little cautious about applying it and wanted to know if anyone has tried it and what they have experienced. The only disadvantage I have seen is that it is expensive. However, in the long run I think we will save money. After it is applied, you cannot bathe them for two days. Then they can get regular baths and it lasts for THREE MONTHS. So far, I love it. Morgan [Posted in FML issue 1669]
