Two species of Hepatozoon organisms have been reported to infect domestic dogs worldwide.

Canine babesiosis is a tick-borne disease caused by a hemoprotozan parasite belonging to the order Piroplasmida within the phylum Apicomplexa.

Immune mediated hemolytic anemia (IMHA) can be a common cause of acute lethargy, depression, weakness, and collapse in emergency patients.

Diabetes mellitus occurs in both dogs and cats and is the most common endocrine disorder in the emergency setting.

Critically ill animals are often presented to the veterinarian for emergency medical management.

Hypoadrenocorticism, or Addison's disease, results from deficient production of glucocorticoids and/or mineralocorticoids by the adrenal glands.

Cardiopulmonary arrest (CPA) is the cessation of functional ventilation and effective circulation.

Without treatment, canine parvovirus (CPV) infection is often a fatal disease ending in severe dehydration, endotoxic or septic shock, and multiple organ failure.

In people, there are four types of heat-induced illness described: heat cramps, heat exhaustion, heat prostration, and heatstroke.

Parasites of the genus Babesia are hemoprotozoan organisms that can infect red blood cells of vertebrate hosts. Although more than 100 species of Babesia have been identified, only two have been reported to infect dogs: Babesia canis and Babesia gibsoni.
