Does Hartz flea treatment work?

Dr. Marie replied:

I can't tell you how frustrated I am over pet store flea products like Hartz, Zodiac and Biospot. They do not work! I don't understand why they are able to sell these products.

This year has been one of the worst years ever for fleas. I think this is because we are creating a population of fleas that is hard to kill. So, when you use a product like Hartz, you will kill some fleas, but the fleas that remain are the strong ones that withstood treatment. So, we end up with resistant fleas.

Unfortunately the products that do work to kill fleas are more expensive. The ones I recommend are Frontline, Advantage, and Revolution.

In many cases, after treating with one of the above products the skin problems will go away as well. However, sometimes dogs will have skin infections as a result of fleas. If this is the case then you will need to have medication prescribed by the vet in order to clear things up. There is no over the counter cream or medication that will be helpful.

I'm sorry for your frustrating experience. I wish I could give you more helpful advice, but it does sound like a vet visit will be necessary!
