Online vet, Dr. Marie

Dr. Marie replied:

In my opinion most over the counter flea treatments like Hartz are completely useless. I get really frustrated that they can sell products like this!

The good news is that if you get a good product like Advantage, Revolution, Frontline or Comfortis you are fine to go ahead and start using it right away.

Here is some more information on fleas for you.
