I read somewhere the other week that if you pay close attention to the way your dog wags its tail, they may be telling you something. The article said that if your dogs tail wags more to the left (the dog’s left side) it meant they were happy. If it was equal distance from left to right, they were content. When they wag more to the right they have negative feelings about something. After reading this I did my own little experiment, and so far its all true. Try it yourself and let me know the outcome.
