His grandfather, recognizing his grandson's interest in animals, passed down to him a number of his personal formulas. After emigrating to Canada in 1988, Dr. Tse spent 6 years adjusting the formulas so that Pets could be treated generically, without the need for a personal examination. The result was his production of a range of effective Chinese herbal remedies which can be used without any knowledge of Chinese Medicine.Nature's Herbs for Pets has been dedicated to the holistic healing of cats and dogs now for many many years.
