Most of us are conscious these days on the long term effects of chemicals on the body. Now geneticists are finding out that chemicals can affect the DNA of the yet to be born, as well as those of us who have been exposed. You would be silly not to be concerned with what is being sprayed around the house. Have you ever considered the effects on humans as well as pets of the flea treatments that we put on the necks of our dogs. I don’t know about you, but my dogs cuddle up to myself and my family. They get on the furniture and share our lives. Chemicals on the dogs coat are bound to be transferred to myself, family and my home environment.
