My 7 mo old lab was alone in my room for about an hour. When i came back i found one of my picture frames on the floor chewed to hell. About half of the frame is missing. The frame in itself is small, about 3"x5". Its like particle board. But theres a little chip of the glass missing, about twice the size of a pencil eraser but half the width. I checked her mouth and theres no blood, but i checked the floor and cant find it. Shes been left alone for alot longer before and has never done anything. Today was different. What do i do? Just monitor for blood in stool? I haven't given her, her night time yet, do i hold off or give it to her?
