First let me say, he is gorgeous. My opinion: he is 7 months old, just a baby. He will learn what's acceptable & what is not. When I was late with dinner, twice Max bit me in the arse. The first time I was shocked ( dinner was a half hour late). The 2nd time, I took him for a walk (he hates his walks) i walked him fast & long. He never did it again. That was 4 years ago.
Max is 75lbs, we play hard together. Some weeks I have bruises on my arms & legs but, he is not trying to hurt me.
Remi will learn, he loves you & wants to please you.
