2 year old Standard Poodle brothers, Iggy and Georgie, with their 12 month pendants on their collars. They wore the collars for 7 months with no fleas or ticks. I love the idea that it’s all natural. Your company was recommended by a groomer who uses your products. No more pesticides for my babies. The third picture is 13 years old Roxie, the matriarch and ruler, modeling her hot pink collar. Thanks for a product that is effective, but gentle enough for seniors.
