Dixie is on Revolution, but she's constantly scratching and chewing at herself like she has fleas. I've checked her from head to toe. No flaky skin, rash, fleas. A girl came into my boyfriends shop with her chi and said hers did the same and she uses garlic powder in her pups food. I've heard of people using this as a natural alternative for fleas. I've also heard that garlic in certain amounts can be harmful. She also said this is another chi peeve to add to the list. What is your opinion?
