 Mine do it too
Lil Bear is bad about it when we come back from being out for a little bit. She will look at us and just bark and bark like we are being chewed out for leaving her. She will go to my mom to be picked up look, at her in the face and start yelling, we think she cuses us out. She will also move her mouth when we talk to her or when she is trying to tell us something.
Moose talks too but she actually talks!! One morning she dropped her red bone on the floor by my bed I told her I was sleepy and not going to get it so she sat on her chair and started growling, I ignored and then she started saying mama, freaked me out since I didn't teach her to say it, and got her bone. She does it whenever she wants something now though I will ignore it sometimes. She will also sit by her water dish and hit it and growl to get more water |
