We’ve written before at HuffPost UK about what it means when your dog starts stealing your shoes, and have shared that yep ― they really do know when we’re sick. But it’d be a very different (and disappointing) world if those were the only confusing signs our furry friends exhibited. For instance, why did my previous pooch bark only at butterflies, and no other insect?And why oh why can’t they stop humping us fearful, unviable humans?The first question likely has no reasonable answer. But to help us get to the bottom (hehe) of the second, Annie-Mae Levy, professional dog trainer and behaviourist at Woofz by nove8, has come to the rescue. So... why do dogs hump us?According to Annie, the rather forward habit is actually often a sign of shyness.“Humping isn’t about being the ‘alpha,’” she explained. “Most of the time, dogs do it because they’re overstimulated or anxious.” She explained that it’s likelier to happen when your pet is in a new or confusing environment or when guests arrive.“
