It truly works for eliminating fleas from dogs. Just a few drops in the drinking water each day BUT it does take about six weeks.I have also sprayed the dog's beds and cleaned rugs and floors every day so it is an ongoing chore to for the six weeks but I am now on top of the situation.I run a Poodle resort so I have quite a few dogs and to have solved the flea problem is an enormous relief.
Apple Cider Vinegar
I use ACV in my rescue dogs' food twice a week and give them diluted ACV rub downs with a wet sponge or rag about every 10 days. There are no fleas on these dogs at all, which I think is a result of the ACV. I also use it full strength for ring worm and seem to be having some good luck with mange.
