I use Comfortis on my miniature doxies. They do just fine with no sickness and eliminates all fleas. I have found nothing else that works. I give it to them and do not give anymore until I see fleas again, I don't want to put anymore drugs into their system than just have to. It usually takes 3 months before having to give another. I have used this since summer of 09. My yorkie is also to small to give this too. She gets revollution for heart worms and takes care of any fleas she may pick up. |
