My father has a 10yr old chihuahua that is very obese. The vet has run serveral test to include blood work, xrays, and stimulus test.
The vet suspected Cushing’s disease and the results were 2.7 prior to the test and 11.9 after. The results were negative for Cushing’s however the vet said that sometimes this test provides a false negative.
The blood work also showed levels of 2624 when he said the normal is 5-131. So basically he has a very enlarged liver and that is all we know.
The vet wants to bring in a specialist, Dr. Parkinson to perform an ultrasound and consult.
Question: Does this all sound correct and maybe on target? What would you do? and what do you think may be the prognosis?
My father loves little Bear so much but I hate to see him invest so much emotionally and financially if there is really no treatment.
Thank you so much for your time.
