One method of determining whether the food you feed your shih tzu is affecting its health or producing problem symptoms is to keep a health journal.

It is time consuming, but will be invaluable for determining whether there is a link between his diet and his condition. You can diagnose or better yet help your vet diagnose your shih tzu's itchy skin, whereas otherwise, it might be impossible and cost you a lot more money in vet bills after your vet has to run test after test based upon the only symptom you report being "itchy skin." You may even still end up with a shih tzu with itchy skin. You can do a little homework on your own and put your money into your own investigations. Then take the entire journal to your vet and show him what you have done so far to determine what is causing your shih tzu's problems, or better yet, solve it yourself and never visit the vet.

In your journal, list the foods you give your shih tzu and their major ingredients, note outbreaks of increased or renewed itching, ear infections or paw-licking, whatever problem you think his diet might be causing. Change the food. Note symptoms. After about six months into your project, go back over your notes to see if symptoms increase when certain ingredients are fed, or do symptoms decrease.

Keep the date, your shih tzu's health problems and assets, results of veterinary exams or tests, the type of food or foods you feed him and the food's major ingredients (this would be the percentage of protein and fat). The major ingredients in any dog food are always listed first.

Periodically look through the data for trends such as: Did your shih tzu's itchy skin or coat problems go down or up when you switched to that "food." Did some foods trigger diarrhea and only go away when you switched to another food?

My tests were simple. I merely changed all my dogs to HealthyPetNet Life's Abundance Dog Food and Treats. The diarrhea problems and loose stool problems disappeared. The dogs I had that were itching because of their diet, stopped itching. I had a few that did have other skin problems (minor) in which I sought the help of a vet for resolution. Other than that, my shih tzu are thriving better than ever before since we switched to HealthyPetNet Life's Abundance Dog Food.

Your tests may not reveal the same. Not every shih tzu is alike. I do have several different bloodlines, however, and the food has agreed with them all, which is kind of unusual. Which food to feed my shih tzu has always been a huge problem for me at Stain Glass Shih Tzu. Based upon my experiences and observations with the shih tzu I presently own, HealthyPetNet Life's Abundance has proved to be the best of all. It could be your tests prove differently. Just keep your journal. Read the dog food labels. Know that the main ingredients are listed first. Then make your decision of whether or not it is the diet of your shih tzu causing the problems you seek to solve.
