Hartz UltraGuard Pro Flea & Tick Prevention Drops For Extra-Large Dogs Above 61 Lbs, 3 Monthly Treatments

I came close to buying one of those expensive flea collars this year, but didn't. And I went online to the pet stores researching all the topicals, too. Then I decided to save my money and buy what I have always bought - Hartz. They have different ones, the basic up to the pro, which I buy. My dogs have been running around a one acre yard for years and only ONE time did they ever have a flea - it was this past winter when I wasn't using a flea treatment. Lesson learned: This stuff works. If it aint' broke, don't fix it. Also, the vet was right when she said they can get fleas in the wintertime. Luckily it was just one flea and I noticed it on the deck before we entered the house. All brands, cheap or expensive, drops or collars, will have bad reviews because not all dogs react to the same ingredients. Doesn't mean they're good or bad. I couldn't chance spending $100 to find out my dogs and their ingredients didn't get along. And it wasn't necessary anyhow, because what I had been using has always worked for all of my dogs.
