It contains Imidacloprid and Flumethrin as active ingredients, which are effective in killing and repelling fleas and ticks by contact.

Being unscented and allergen-free, it’s generally suitable for dogs starting from 7 weeks old, including puppies. This wide age range makes it a good choice for many dog owners.
