What are the causes of coccidiosis in dogs?

Coccidiosis in dogs is caused by protozoan parasites belonging to the genus Isospora. These microscopic organisms live in the intestinal tract of dogs and are spread through the fecal-oral route.

Here's a breakdown of the causes:

* Ingestion of contaminated feces: The primary way dogs get infected is by ingesting oocysts (the parasite's egg-like stage) found in contaminated feces. This can happen through direct contact with infected feces or through contaminated environments like parks, kennels, or shared water bowls.

* Poor sanitation: Insufficient sanitation in kennels, breeding facilities, or even at home can lead to the accumulation of infected feces, increasing the risk of exposure.

* Stress: Stress can weaken a dog's immune system, making them more susceptible to infections like coccidiosis.

* Compromised immune system: Dogs with compromised immune systems, due to illnesses, medication, or other factors, are at higher risk of developing coccidiosis.

* Young puppies: Puppies are particularly vulnerable to coccidiosis due to their underdeveloped immune systems.

* Overcrowding: Overcrowded conditions, especially in shelters or kennels, increase the likelihood of fecal contamination and spread of the parasite.

Important note: Coccidiosis is not contagious between dogs and humans.
