tail wags are not always a sign of happiness


We’ve all been told that a happy dog is one that wags its tail, but scientists have now discovered that this is only half true. Happy and relaxed dogs wag their tails more to the right, while anxious or nervous dogs wag more to the left.

Researchers monitored the heart rates of a test group of dogs when they were shown various tail movements of others. When they saw other dogs wag their tails to the right, they were relaxed and calm. However, when they saw the tails move to the left, their heart beats increased and they appeared more anxious.

Next time you’re at the dog park, observe these subtle signs to see if your dog is happy or stressed.
