== Introduction<br> ==
Coccidiosis in dogs is much rarer than the common disease presentation in ruminants and poultry. Transmission of coccidia is via the faeco- oral route; ingestion of the oocysts.<br>
There are 2 common and 2 less common ''[[Isospora spp.|Isospora]]'' species that can occasionally can cause disease in dogs. Often the dog is immunosuppressed or in very poor condition in order for the disease to occur as small numbers of oocysts are not pathogenic. Even if the faecal oocyst count is high, other causes of diarrhoea should be investigated. Both species of ''Isospora'' have little pathogenicity.<br>
<br>
== Clinical Signs<br> ==
Diarrhoea and weight loss. There may be anorexia and fever in severe cases.<br>

== Diagnosis<br> ==
Presence of a very high number of oocysts in the faeces, plus previous exclusion of other causes of diarrhoea. History of overcrowding or unhygienic condtions may also be indicative.<br>
<br>
== Treatment and Control<br> ==
Sulfonamthoxine or Trimethoprin are the treatment of choice in dogs.<br>
Investigation should be undertaken into living conditions of the dog, or pre-existing medical conditions that may make the animal susceptable.<br>
