The article is very good covering pre diagnosis potential aliments your dog may experience, holistic and medical treatment with drug therapy and pointing out that it is sometimes extremely difficult and a long process to obtain the specific diagnosis of Cushing's. My dog an 8 year old female bull-boxer-pit mix (a rescue I had for only 4 years) showed the first sign at 4:25am on a warm June morning, when she had a grand mal seizure. Then the slow and steady need for more water. We thought all the "water" on her bed in the morning was drool - no smell, no yellowing but chronic, along with very frequent seizures. I see a holistic vet and we ran so many tests and ruled out so many things and I tried acupuncture, manual chiropractic adjustments, diet and supplement changes. The concerns with her wellbeing didn't improve. Several months later the diagnosis of Cushing's Pituitary (tumor) - like the last paragraph on page 20. We opted for medication to control the Cushing's but the tumor grew. She crossed the Rainbow Bridge about 2 months after the diagnosis and starting medication. I concur with the article, in my experience, this is a hard to diagnosis properly illness. My dog seemed to present what looked like uncorrelated symptoms and atypical of the "usual" Cushing's.
