Why are there still fleas after deworming the dog?

After deworming the dog, there are still fleas on the dog. It is not a problem with the medicine, nor is it a problem with the method. It is because fleas are too vital. Dogs can become infected with fleas when they play in the grass or come into contact with other small animals. Dogs may be infected with parasites even if they stay at home. People can also act as carriers and bring parasites and their eggs home through their clothes and shoes, indirectly infecting dogs. So don’t think that your dog won’t have fleas if he doesn’t go out. There is still a high chance that he will be infected.

How to kill fleas

Flea colonies are evenly distributed, with about 50% eggs, 35% larvae, 10% cocoons and 5% adults. When fleas are found on your dog, it actually means that your home has become a flea habitat. It is not enough to simply kill adult fleas. The selected anthelmintics need to inhibit the development of flea eggs and young fleas at the same time, and at the same time keep the environment clean. It is also necessary to clean the dog's mat and vacuum the areas where the dog frequently moves to suck out the eggs.

Prevention is better than cure

Even if the adult fleas on the body can be quickly killed, a larger number of flea eggs and flea larvae will continue to develop into adult fleas in the home environment and infect the dog again. . It usually takes 3-4 months to completely eliminate fleas in the environment. Rather than spending a lot of time and energy dealing with infected fleas, a more scientific approach is to use external anthelmintics once a month. Prevention is better than cure. Although fleas are pervasive and tenacious, owners only need to do preventive control and clean the environment every month.
