Ticks and fleas can pose a serious risk to your dog as well as to the rest of your family.

Threats to your pet include:

  • Acute discomfort: Scratching, chewing, biting and restlessness
  • Flea allergy dermatitis (FAD): A common veterinary, dermatological condition1
  • Anemia: A risk for young or smaller pets, or debilitated adult pets as a result of severe infestations
  • Tapeworms infections: Spread through the ingestion of infected fleas
  • Lyme disease: Bacterial infection resulting in fever and swollen joints2
  • Ehrlichiosis: Blood infection transmitted by the brown dog tick3
  • Rocky Mountain Spotted Fever: Fever, a stiff, awkward gait and the development of seizures3
  • Anaplasmosis: A blood-cell infection similar to Lyme disease3

Threats to humans include:

  • Allergic reaction: Often resulting in small, raised lesions called papules that can be red to purple in color. The severity depends on a person’s allergy to the bite.4
  • Tapeworms (Dipylidium caninum): Generally spread through infected fleas found on both dogs and cats. While rare for adults, the ingestion of an infected flea by a child can result in a tapeworm infection.4
  • Typhus: A group of infectious diseases often resulting in a sustained high fever (typhus fever), headache, delirium and red rashes. Two kinds commonly originate from flea bites:5
    • Flea typhus: A typhus caused by Rickettsia felis. The cat flea is the only currently known vector for this bacterium.
    • Murine typhus: A bacterial form of typhus commonly transmitted by rodent fleas but can also be transmitted by fleas found on pets.
  • Plague: Rodent fleas can be carriers of bubonic plague, or Yersinia pestis. If these fleas make their way onto dogs and cats, they pose a higher risk of leaving their animal host to bite humans who come into contact with them.4
  • Lyme disease: Bacterial infection resulting in rash, fatigue, joint pain and flu-like symptoms.6
  • Rocky Mountain Spotted Fever: Symptoms include high fever, chills, muscle aches, nausea and vomiting.7
  • Ehrlichiosis: Bacterial illness resulting in symptoms that include fever, headache, nausea and fatigue.8
