To ensure a proper diagnosis, we often need to examine your pet. We begin a medical assessment by looking at your pet’s eyes, ears, and skin and checking his or her cardiovascular, neurological, gastrointestinal, and skeletal systems for any abnormalities. We will perform blood and/or urine tests as necessary to check your pet’s kidneys, liver, pancreas, and endocrine system, including the thyroid and adrenal glands. Based on your pet’s condition, we may recommend further diagnostic tests, such as radiography (x-rays), endoscopy (internal scoping), ultrasound, or biopsy.
