We breed dogs in Germany and have relied on this book for years. It has helped many of our dogs. The information is easy to find and comprehensive.
It does help to read a general book on homeopathy first, but it is a great reference when it comes to every day issues.
Like other books on homeopathy, this book is best used together with a comprehensive materia medica. It's important to keep in mind that the listed remedies are suggestions only and may or may not fit the individual patient's symptom picture. Having said that, this book covers a wider range of ailments than most books on veterinary homeopathy. The introduction to homeopathy section, however, is very brief and there is little information on taking a case and selecting the correct remedy, so this is not the best book for someone new to homeopathy (check out books by Dr. Don Hamilton or Dr. Christopher Day first).
In addition to the guide to canine ailments, there are descriptions of thirteen constitutional types, excerpts from readers' letters, and some interesting essays on veterinary homeopathy including one on homeopathic alternatives to vaccinations.
