Bf doesn’t like my dog..

I need advice. I've had my dog for 4 years. I recently started dating someone and it has gotten pretty serious quickly. I recently found out he is not fond of my small dog – he says he is just a lot for him (my dog really likes him so gets really excited when he shows up, wants to be around/on him when he's here, sleeps next to him). So he essentially told me that he doesn't think he could handle him being around him 24/7, like in the future if we lived together. I asked him what he would expect to happen and he said he would try at first but it'd probably be a problem and I also need to think about his feelings but to not overthink it right now because it is in the future . I just need opinions and advice on this situation. Am I overthinking/over reacting too much/early? It just worries me because my dog is my baby (which he disagrees and states he is not, he's my dog)..

Just an edit to clarify: I would NEVER get rid of my dog for anyone. 🙂 just asking for opinions and advice in general, thank you 😊
