Query: Information in the WDJ added years to GS's life

We have subscribed to the WDJ for many years and there is always something new to learn. The researched information, reviews, and recommendations have proved invaluable throughout. Especially helpful were the articles pertaining to health care for our aged dogs: including lists of the WDJ's approved top dog foods and articles on nutritious diets. In particular, the excellent and well researched information regarding Yeast infections helped our German Shepherd live happily for an additional 2 years after the Vet gave up on her. Our family is extremely grateful and indebted to the staff and authors of the Whole Dog Journal. Thank you!
