When you first arrive at the veterinary clinic, the veterinarian will start with a physical examination. This will allow her to take note of all your dog’s symptoms. If your dog is experiencing any coughing or wheezing, she may want to take a radiograph to get an internal look of the lungs. This will help rule out pneumonia, bronchitis, or any other respiratory related illness. If your dog’s skin is irritated, the veterinarian may take a skin scraping to check for external parasites or bacterial overgrowth. If your dog has watery eyes, the veterinarian may perform fluorescein staining to check for a scratch on the eye that might possibly cause the watering.
Kidney and liver function will be verified with a urinalysis. Blood work will be performed to give the veterinarian a broad look as to how the internal organs are functioning. A complete blood count (CBC) and chemistry panel will provide the veterinarian with needed information for proper assessment. A packed cell volume (PCV) may also be performed to determine hydration status.
With contact or inhaled allergies, you can also perform allergy tests. One test is called intradermal testing. This involves injecting the skin with the suspected allergen and waiting to see if an allergic response occurs. There is another allergy test that involves taking a blood sample and sending it off to a special lab for them to test it. With this test, they can determine what objects your dog is allergic to and how severe. While this test sounds the easiest, it can be expensive.
