This book is in the form of a magazine. We have two rat terriers and the descriptions of this dog are to the tee. It has great tips and advice on topics I have wondered about and topics I didn't know about such as training and tricks. Rat terriers are smart, active but not hyper and very loving. I learned that I need to socialize my puppy more because she is really starting to become clingy and attached to me. I like it at this age, but she may become possessive in an undesireable way when she gets older. Good information!
