When you first arrive at the veterinarian’s office, she will begin with a physical examination of your dog, and will verify his vital signs. The veterinarian will also discuss the symptoms your dog is experiencing, taking note of the history behind them. If your dog is vomiting at the clinic, the veterinarian will inspect the contents for any clues to the cause. If your dog is having diarrhea, the veterinarian will perform a fecal test to rule out any internal parasite or bacterial overgrowth.
If your dog is experiencing infection or soreness of the ears, an ear cytology will be performed. The veterinarian takes a sample of the buildup in your dog’s ears and looks at it under the microscope. This will allow the veterinarian to identify what bacteria or yeast is growing in the ears, if any. If your dog has a skin condition, a skin scraping may be taken to rule out bacteria or external parasites.
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. If your veterinarian feels it is necessary, she may also perform a urinalysis for further evaluation of kidney function.
When it comes to diagnosis of grain free allergies in dogs there are very few diagnostic tests you can run. A dietary trial is the most frequently used method. In a dietary trial, you have to feed your dog a novel diet, meaning you feed him a diet without the grain free aspect whatsoever. You have to feed your dog the novel diet for at least 90 days before you can get a reliable diagnostic. After the 90 days, if resolution of the allergic signs occurs, you then must reintroduce the grain free aspect to his diet. If a relapse in allergy symptoms occurs once the grain free aspect is reintroduced, then you know the source.
Bicom testing (bioresonance) is another method of determining a food related allergy in your dog. Many holistic veterinarians use the Bicom testing with an extremely high success rate, but other veterinarians may not have experience with it. If you look up Bicom testing, some methods are potentially used to ‘retrain’ the body’s electromagnetic waves to relearn the allergen does not actually pose a threat and should therefore stop producing an allergic response. The veterinarian takes a blood sample from your dog and tests different food items and substances to see if it has a ‘good’, ‘neutral’ or ‘bad’ response.If it is determined that the grain free diet is not good for your dog, then you simply remove that food from his diet and the allergic symptoms should stop. One downside to Bicom testing is that it is unable to provide you with what exactly in the dog food that your dog is allergic to, just that an ingredient within it is not good for your dog.
