What Are Fleas And Why Are They Dangerous

Fleas are skin biting parasites that thrive in warm and moist environments. The majority of fleas (95%) are found on mammals, while only 5% are found on birds. These insects live by sucking on blood from their host. However, a dog infested with fleas won’t have only blood sucking parasites.

Here’s how. Fleas have four stages of their life cycle – egg, larva, pupa and adult. Depending on environmental conditions, their life cycle can last from 2 weeks to several months. This basically means that if you have spotted only a couple of adult fleas on your dog, it might be that he is actually infested with a greater number of flea eggs and larvae.

Their saliva is known to be an allergen that irritates a dog’s skin resulting in a lot of itching, scratching and potentially causing flea allergy dermatitis.

Not only, but these parasites can also spread several diseases (flea-borne diseases) to your dog:

  • Tapeworms
  • Anemia
