K9 Complete Care: A Manual for Physically and Mentally Healthy Working Dogs is a book aimed at the owners, trainers and handlers of working dogs, although there is much for pet owners as well. Authors Resi Gerritsen and Rudd Haak, themselves experienced with training and handling working dogs, provide a detailed overview of caring for a working dog. They begin by looking at whether dogs should be trained for work, and what considerations should apply before a dog is put to work. Safe warm-up and cool-down exercises are offered, as well as ways to improve the canine's general fitness level and ability to endure the stress of canine work. Among other basic health care topics in this book from Temeron Books Inc., there is also a chapter on the dog's ability to endure extreme heat and cold and ways to prevent illness and injury from working in those extremes.
