Cushings is an extremely complicated condition to both diagnose and treat but with such a high reading on an acth stimulation test is is extremely likely in this case. There are additional confirmatory tests such as a urine cortisol:creatinine ratio and dex suppression tests which can be used to further investigate. If she has no symptoms at all then it may be an option to withold treatment and monitor very closely, keeping a symptom diary to track any changes. In some dogs, the abnormal excess cortisol can actually provide antiinflammatory effects improving quality of life and treatment can actually allow other symptoms to emerge. You should be aware that untreated cushings may indeed shorten life expectancy
