  • Insectoacaricidal drops on the fork - these remedies are suitable for any breed of dogs, and some - even for puppys. Particularly known drops are Stronghold, Frontline, Hartz, Bar. In the line of each manufacturer there are preparations for dogs of different breeds and age, therefore it is not difficult to choose the most suitable drops. Apply them as follows: from the pipette the liquid drops on the forele in the neck of the dog( some drugs - in several places along the spine) and carefully rubbed into the skin. After that, through the network of hypodermic blood vessels, the insecticide spreads throughout the body and poisons parasites that suck in the blood or feed on the animal's skin. Drops are the easiest to use long-term funds. Only occasionally they can cause an allergy to the animal. Lice in dogs: is it true or a myth?

Such measures will be enough to ensure that your dog has never learned what kind of lice and hairworms.
