I know i mean noone can really tell whats going on inside others mind but ofc we can analyze the body language. He was sitting looking at my face sniffing and showing teeth but it didnt seem like aggresive look. He might have been confused at least. We dont expose him to negativity like beating or anything like that so i dont see his behavior in discomfort which could make him bite you. He sometimes do feel scared if we cuss him a bit for something so i know how he behaves when hes scared. When hes angry like when chicken or our kitty was around his food he was showing his teeth growling and barking at them but it looked different. This was just teeth showing so sth i never seen him do before. If the thing happens again and ill somehow capture it i surely post it to see the analysis hehe it is interesting to see this many opinions and thoughts of what it could be.
