We have had our girl from 10 weeks old and she is now a lovely well rounded girl. She exhibited typical puppy behaviours that had us tearing our hair out some days but has always been such a loving and cuddly girl. Recently when it is just me in the house with her if she is playing she often starts to be aggressive to me. Barking in my face and biting at my arms or legs whatever is close to her. She is crate trained but will not listen if I tell her to go into bed and will run around the room frantically biting me if I try to get a hold of her. If and when I finally do grab her by the scruff she will snarl and bite as I put her in the cage. I leave her to calm down for 5-10 minutes and when she comes out of the crate she will be fine again. However the frequency that these aggressive episodes are occurring is increasing and I don’t know what to do. I’m scared me shouting at her and dominating her to put her in the crate might be making it worse? But I don’t know what to do otherwise. I’ve tried to do some research but not found any appropriate articles and any suggestions would be well appreciated. Thank you.
