For those of you who know me from my past posts about my German Shepherd, Yuma, know that I have been working with him quite a bit on several things. Well, he is becoming a well mannered boy (in some cases he isn't so much ) and I am continuing to work with him. His most recent issue is showing his teeth to me and growling at me when he is in trouble. PLEASE NOTE THAT HE DID THIS NOT FROM A SPANKING BUT FROM ME SCOLDING HIM. Just a few seconds ago he was eating his afternoon meal and as I walked by I went to scratch him on the rump as I always do. From puppyhood he has been taught NOT to growl at me and allow me to take his toy, food, treat, etc. without the guarding instinct. Never has he done this before until now. The growling is becoming a serious issue and I fear him biting. Each time he has done it before (which now totals 2 or 3) it was for being scolded for not coming inside when asked or for chewing on something he wasn't supposed to. Also take note that when I say "scold" I mean talking to him sternly and my body language showing that I am not pleased. NOT getting in his face or anything that crosses his boundaries. Normal reaction to the scolding is he would turn his head and hide it with a "I'm so sorry" sort of look then it was over with. Please help me with this. I don't know what has triggered this but I have considered that it is because he is nearing 2 (will be at the end of May) and maybe his hormones have the effect? I plan to neuter him soon regardless.
