Review: It's unbelievable the prices vets charge for flea and tick protection, in fact, the OTC applications aren't that cheap either. We've this product for 2 years and it's worked just fine. Note, we own a Shih Tzu which is an indoor dog, but we take him out several times a day and he's stayed free of ticks this past summer. We recommend.
Review: It works for my beagle, who loves to go on walks and play in the long grass. i washed my dog after a walk in the woods, and I actually saw dead ticks coming off of her in the bath, so any ticks or fleas that get on her die from a bite. tips for others who want to use this: 1. I always part the fur to make sure the liquid touches the skin, and I apply it to three different places on my dog's neck and upper back. 2. I also make sure to rub the liquid into the skin a little bit. I wear gloves to make this process safer. 3. I do not let my dog get wet for 3 days after applying, no baths, no walks in the rain, nothing wet. 4. i always make sure to apply this on the same day every month, even over the winter, to make sure she is always protected.
