Input: Bought this for my dog that suffers constant itching all over his body. Was skeptical at first but after a week of giving it to him I didn't see any change in the itching area so thought I'd try again. Well today is day #6! Still no relief and having some pain but still can't get back inside. We will continue feeding this mixture until the bottle is empty, then go on prescription flea medicine.
Output:
Good Review
