1 tube = one application and protects for 4 weeks.
Part the fur and apply the repellent to the skin along the back line of your dog from the neck to the base of the tail. Thanks to the fur structure, the product will then spread all by itself.
If you feed several four-legged friends with it, always make sure that they do not lick each other after use.
In addition, the treated area should not be touched by people until the product has completely dried.
