Pomeranian only likes me
So I adopted a 7 month pomeranian puppy 2 days ago, he is the cutest little thing and very playful. Since we got him, he is always following me around the house, and always trying to get my attention. If I am in a room with other people he will come in and socialize with them, but once I leave he follows me, when I use the bathroom or go in my room he waits for me outside the door. My mom told me that when I leave he just sits by the door until I come back. Also, whenever I leave/arrive he is very excited. I think this might be a case of separation anxiety. My question is, what can I do to get him to stop following me/trying to be in the same room with me? This dog was meant to be a family dog, but he only seems to like me.
