Apparently, researchers have just discovered what we dog lovers have known for donkey's years - that dogs smile when they are happy.
I wonder how much money they wasted on managing to find that out for themselves!!!!!
I for one, would have told them F.O.C.
It is the same as some of these so called dog experts, who say that you shouldn't grin at a dog, because it will see your bared teeth, and think you are being aggressive to it.
Rubbish - going by the reaction of my dogs, they are well aware that I am happy with them when they see my teeth as I am grinning at them.
