Zoey does something similar. She has a bit of a "temper" if you will. She doesn't go after people per say but she barks/growls at anyone visiting. The only time she does the grab & shake is when she's really upset. Like if Magnus takes her treat/bully stick. She'll grab whatever is closest to her.
Long story short, I wasn't able to correct her behavior 100%. The best I could do was make sure she's aware enough NOT to bite humans. She's very smart but also extremely stubborn. I still do reprimand her when she loses her temper like that but she's 3 years old now so I'm not really holding my breath that she'll stop being like that anytime soon. LOL |
