I been helping a friend of mine doing some part time pet grooming. We sweep up bags of dog hair every day. She has told me she uses it around her flowers to keep rabbits and other critters away. She also has clay soil and said that dog hair is high in nitrogen and helps with her soil (clay). Now while I don't doubt what she is saying, I've just never heard of pet hair. Human hair, I've heard of-it keeping small critters out of the garden. Has anyone used pet hair or know of its uses in the garden???
