It's been several years since I purchased this. I'm selling it because I started using "Frontline" for my pet. To reduce the thickness (for easier mailing), I will ship the product separately from the box. This is for medium-sized dogs, providing flea and tick control with an effect lasting approximately one month. Contains 6 doses. - Product Name: Sunspot - Contents: 6 doses - Suitable Weight: 5kg to 15kg - Duration of Effect: Approximately 1 month - How to Use: Apply to the back - Ingredients: Phenothrin (Pyrethroid) Thank you for looking.
