75 days
Use
On the animal's back, at the beginning of the neck, fold the hair so that the skin becomes visible. Cut off the tapered end of the pipette and then squeeze the contents over the skin several times so that the spot on it is completely emptied directly into one spot. 1 pipette will alert fleas and ticks for 15 days. The 5 pcs box thus protects for a total of 75 days.
