In biology, a parasitic relationship is defined as a relationship in which one organism (the parasite) lives on or within the other (host), and may cause the host harm.
Parasites are organisms that find nourishment by living on or within another animal. Dogs fall victim to several parasites, some of which are external, such as fleas and ear mites, and some intestinal, like intestinal worms that affects puppies soon after their birth. These parasites can lead to many dog illnesses, including secondary skin infections and Lyme disease. Some of them are also known to cause zoonotic diseases, i.e., diseases that can be transferred from animals to humans.
Taking into consideration the threat to your pet's and your own lifeā€•or that of your family for that matter, it's but obvious that you need to take a serious note of the issue and deal with it at the earliest.
