There are a few different choices......just please use something! I've just been through a real ordeal with my Halo. She was sick for a week, vomiting and not eating at all. The vet was treating her with different anti-biotics; nothing was helping. On the second day to the vets for fluids, I noticed a really red spot on her tummy. Turns out it was an embedded tick!

He started treating her for "tick fever" with doxyclycline and she is so much better. She'll probably have to be treated for 4 - 6 wks to make sure she's completely ok. Anyway, I was treating mine yorkies with Comfortis. I was not aware that it did not work for ticks. I feel so stupid and so bad for my Halo having to be so sick because of me!

Anyway, we are going back to Advantix. It worked great before, but the thought of just giving a pill (comfortis) instead of putting the Advantix on them....just sounded so much easier. Well, after a sick baby and 500 bucks later.....go with Advantix.
