Approach to Chronic Enteropathy Practice Test

In these chronic canine enteropathy categories, how a disease responds to treatment is the key distinction. Food-responsive disease (FRD) typically improves with a diet change and often has a favorable prognosis that may not require ongoing pharmacologic therapy once the diet regimen is successful. In contrast, antibiotic-responsive enteropathy and immunosuppressant-responsive enteropathy (ARE/IRE) show more variability in outcome. Some dogs may improve with antibiotics or immunosuppressants, but relapses are common and many require ongoing or long-term therapy to control clinical signs. This keep-them-going nature of ARE/IRE reflects their more unpredictable course compared with FRD.

So the statement that ARE/IRE have more variable outcomes and may require ongoing therapy best matches their typical clinical behavior, whereas FRD tends to do well on diet alone. The idea that FRD has the best prognosis with diet alone aligns with FRD, not ARE/IRE. And ARE/IRE do not strictly “always” respond to immunosuppressants, and ARE can involve antibiotics, so those options don’t fit as well.
