Trainer Nic has just read this book by Martin McKenna and found it be very resourceful when it comes to learning about basic dog body language and how to understand what your dog is telling you!
Having learnt from growing up and living with stray dogs, Martin has learnt a lot about how they communicate, their heirarchy and how it works and how clear rules in the dog world need to be listened and adhered to or else there will be problems in the pack.
