my dog is a 2 years old shiba inu, male. sometimes (maybe once a month), he won't finish his meal, maybe only eat half of it, and then just look at the bowl or laying next to it. I used to just put the kibble away and he become very nervous and bites his toy, once i put the kibble away and he becomes fine.
yesterday i was out of town for business, and my roommate fed my dog kibble. he was doing this again. and bites my roommate when he tries to get up from the sofa.
why my dog like this? is he don't like the food? how can i stop this from happening in the future?
