Not as convenient as pills, but very effective
Our greyhounds were having recurrent hookworm infections despite their previous medication being used to treat all manner of worms. So our vet suggested we switch them to this. It is not convenient to use since it is a liquid that goes on their fur. It needs to be left to absorb for 30 minutes and they can not lick or rub it off. Aside from that, we have found it to be a very effective medication for them. We have not had a hookworm infection since we started using it 3 months ago.
