My warning to everyone is never purchase an Over-the-Counter flea and tick prevention. These products contain chemicals that have a high rate of reactions. I work in a veterinary clinic and I have seen burns, seizure, and rashes to name some side effects. Your best method of preventing parasites is to use products from your vet clinic. In the long run it will save you medical expensive related to adverse reactions of these poisons.
