SABUNOL GRAY COLLAR 50 CM Sabunol GPI is a modern anti-tick and anti-flea collar for dogs, effective and comfortable to use. The unique combination of three ingredients (permethrin, imidacloprid and geraniol) ensures effectiveness for 3 months. The tests have confirmed high local and general tolerance of the collar, which makes it safe for dogs. Controls ticks and fleas for 90 days. METHOD OF USE Remove the collar from the sealed packaging, adjust to the circumference of your dog’s neck, and put it on. When the collar is worn, the active substance is released and distributed over the skin and hair of the pet, killing parasites through contact. The effects of the collar use are visible after 48 hours.
