In this fascinating book, you'll find out what's going on behind your dog's soppy grin - and why they like to run in circles before lying down, or roll in fox poop. You'll discover what's normal and will never change, but also if you should be wrestling them into the car for a visit to the vet. Safe to say, your dog will be mighty annoyed if they find out that you're hot on their t(r)ail.
