I think every person that has a dog or cat should read this book. People really need to be educated on what they are putting into their animal companions. Vaccinations aren't bad but we do over vaccinated and also give too many vaccinations at the same time. The book has a lot of good facts that most people do not know and also information for further reading. Its you who has to take care of your animal companions welfare. Yes majority of vets love animals otherwise they would not be in the business. The key word is business they get more money when an animal is vaccination frequently. Vaccinations should be kept to a minimum and if a animal is getting more then one vaccination it should only be 2 at one time and then wait awhile for the others (least 6 weeks) There are many people who have started to go vaccination free and their dogs are perfectly fine and healthy. The book also shows that there is no evidence that frequent/yearly vaccination keeps an animal healthy.
