"The Culture Clash: A Guide to Understanding the Human-Dog Relationship, Training Based on Animal Learning Theory and Behavioral Science" Jean Donaldson / Mina Mizukoshi / Rie Hashine I've only read it once, so the contents are clean, but there is some yellowing due to long-term storage and aging. (Please check the images for details) Please understand that this is a used book before purchasing. I have a dog. I try not to let the dog into the room where I store the items, but if you are concerned, please refrain from purchasing. Returns are not accepted, so please ask any questions before purchasing. I usually ship within 1-2 days, but I may be away on a sudden business trip, so if you are in a hurry, please contact me in the comment section before purchasing. I review the price from time to time. I am selling at a low price including shipping, so significant discounts are not possible. (If you purchase multiple items, please contact me in the comment section) #DogTraining #DogBehavior #DogTraining"
