Mature dogs infected with coccidia usually do not require any special treatment due to the mild nature of their symptoms. Most cases of coccidiosis resolve spontaneously within a few weeks even without treatment; this is called a “self-limiting infection.” However, young, weak, sick dogs may need to be hospitalized, so that they can be given intravenous fluid replacement to counteract the dehydration caused by severe diarrhea. A number of oral and injectable medications are effective against coccidia organisms, including trimethoprin-sulfa, amprolium, furazolidone and sulfadimethoxine, among others. New drugs are always being developed. Severely affected animals should be isolated from other animals if possible during their treatment.
No particular treatment protocol has yet been established as being “the most effective” against clinical coccidiosis.
Coccidiosis is usually quite treatable in companion dogs. As with most illnesses, treatment should be accompanied by regular, exemplary hygiene, a high-quality diet and a good, healthy living environment.
