We have a cottage, two dogs and three cats, children play in the sand all the time. As a result, both were diagnosed with worms after a preventive examination. It is difficult to say what or who became the source of the infection. But we had to cure this disease in all members of the family, including animals. That's the rule. And I believe - the right way. The only problem we faced was the choice of the drug. On the one hand, it is desirable that the medication has a broad spectrum of action; on the other hand, should not cause side effects. My children suffer from allergies, so I treat almost all synthetic drugs with caution. Aware of this fact, our family doctor recommended that we take a closer look at Bactefort. This is a new drug to fight worms. She gave us a brochure, but added that it can be difficult to buy those drops / capsules at a pharmacy, so it's best to order them online https://fitcrasher.com/bactefort/.
