Plus, it has several 100x the effectiveness of standard antiseptics! The EN13727 test has shown it to be 99.999% effective, which other antiseptics struggle to achieve, and it has unbeatable log 710 results – 99.99999%!

All that and still so gentle to the skin your pet won’t even know it’s there – wow!


Just spray Leucillin directly onto the skin. Apply liberally. Recommended for use 3 times a day.

    What a wonderful company. This is the first time I have used and their customer service is amazing. They responded to my query in minutes and had a replacement send out the next day.

    Great value for money, easy to use website. Just wished they sold pet food, then I could use then for everything!
