confused

Hi everyone! It's my first time posting on here:) I just needed some advice... so my boyfriend and I have been dating for 2 months. He's really sweet and I can see us lasting a long time, but he's literally obsessed with my dog. I know this doesn't sound like a big problem, but she is 90% of what we talk about and when she is with us he pays no attention to me. Then when I bring it up that it bothers me I say that it's fine and he says it's not and he's sorry but he keeps doing it. I just feel like he cares more about my dog than me :/ what should I do?
