Connie , Rosi does this, like when we are outside and she finds something, she will try to protect it,if i put my foot there, she goes nuts, and bites my foot, not hard but... like she is saying , hey this is mine
Trust me we have our go arounds over this, i 've had to put cloves on before to get things away from her, 99 % its outside. I have never let her get away with it and whatever it was , it was mine
she does not do it very often anymore, but i have no doubt she will do it again. She did this to my Mom when someone was at the Door and Mom put her foot by the door to prevent her from going out... other then that she is never agressive, and loves everyone...
