My dad’s dog bites at my feet and ankles when I visit, which he only does to me even when there’s others in the room. Before he does, I notice he lingers around me and will act nonchalant before doing so. He also sometimes will growl at me when no one is home but not in a totally scary way. He clings to my stepmother and when she leaves he gets very sad and won’t leave the couch and if he does come near me it’s for a quick second. He won’t accept treats and honestly acts weird, does this mean he has some aggression towards me? I’ve been trying to be more assertive and stern instead of showing fear like I used to.
