our four year old male JR ( normally very loving and has never bitten etc) has recently started growling if we put our face close to his .
he used to love this close affection and cuddles etc
i know its nuts to some folk, but we often give him a kiss on the side of his face.
He has always liked this ( or seemed to)
Now, he growls...
Is this known to the form, as a problem that develops?
If so, is it known why?
