SNAP 4Dx Plus Test

  • The most trusted pet-side vector-borne disease screening test
  • Efficiently test for heartworm disease and tick-transmitted pathogens as recommended by the Companion Animal Parasite Council.
  • Test annually to help prevent the spread of heartworm disease, ehrlichiosis, Lyme disease, and anaplasmosis while increasing awareness of these vector-transmitted infections.
  • SNAP tests provide reference laboratory quality technology for superior diagnostic accuracy at the point of care.

Blood Parasites:


Heartworm disease has been found in dogs in all 50 of the United States. While heartworm is both treatable and preventable, it is a serious and deadly disease that may show no clinical signs in its early stage. Screen annually to find even low worm-burden patients sooner and more often, and begin treatment when you can do the most good.

Lyme disease

More accurately identify Lyme disease in clinically and sub clinically infected dogs with proven C6 ELISA technology. The SNAP 4Dx Plus Test identifies antibodies that are produced only as a result of a Borrelia burgdorferi infection.


Detection of antibodies to Ehrlichia canis or Ehrlichia ewingii indicates tick exposure and the transmission of infectious agents. Additional testing is recommended in these patients to determine if there is an active infection. Controlling the infection early is the best way to protect your patients from chronic disease.


Annually screen dogs to identify exposure to Anaplasma phagocytophilum and Anaplasma platys. Early detection improves patient prognosis and reinforces the importance of tick control.

Mosquito & tick-borne diseases in Florida

You know your dog better than anyone else. That's why your role as the "watchdog" for these infections is critical. Your dog can be exposed to these infections in almost any outdoor location where ticks and mosquitoes can be found, and risk varies from region to region. Review the infection descriptions below and watch for the most common signs associated with these diseases. Symptoms may be hard to detect in the early stages so we recommend this parasitic disease screen at your dog's annual checkup. Work with us to find infections early, because early intervention is important for a lifetime of good health.


  • Heartworm: Mosquito Florida risk: 1 out of 72 dogs Heartworm is a parasitic infection transmitted by mosquitoes. Symptoms may include mild persistent cough, fatigue, being tired after moderate exercise, weight loss, and reduced appetite.
  • Anaplasmosis: Brown Dog Tick Deer Tick Florida risk: 1 out of 152 dogs. Anaplasmosis is a bacterial infection transmitted by deer ticks and brown dog ticks. Symptoms may include lack of energy, lameness, swollen or painful joints, and loss of appetite.
  • Lyme disease: Deer Tick Florida risk: 1 out of 112 dogs. Lyme disease is a bacterial infection transmitted by deer ticks. Symptoms may include lameness, reluctance to move, swollen or painful joints, lack of energy, and urinating more.
  • Ehrlichiosis : Brown Dog Tick Lone Star Tick Florida risk: 1 out of 104 dogs. Ehrlichiosis is a bacterial infection transmitted by brown dog ticks and lone star ticks. Symptoms may include loss of appetite, depression, lameness, swollen or painful joints, bloody nose, and pale gums.
