Review on 🐶 Hartz UltraGuard Flea & Tick Collar for Dogs and Puppies -- 7 Months Protection, White, Up to 15-Inch Neck Size by Dave Hammon

Tetrachlorvinphos (TCVP) is an organophosphate pesticide, toxic to the nervous system and a known carcinogen. In large doses, these chemicals can also harm or kill cats and dogs, and in extreme cases even poison humans. Most commonly, at lower levels of exposure, these chemicals produce a variety of symptoms of intoxication, many of which can mimic common diseases; These include nausea, vomiting, diarrhea, wheezing, sweating and watery eyes. More severe poisoning can cause muscle spasms, salivation, convulsions, respiratory paralysis, and death. Some recent research suggests that exposure to this type of pesticide can impair neurological development in children, leading to common disorders including motor retardation and attention deficit disorder. .
