Our puppy doesn’t like my bf

Hey everyone, I need some advice.

Me and my boyfriend adopted a puppy around a month ago. It was my boyfriend's idea – it was his dream to own a dog. I'm more of a cat person but he convinced me to adopt a dog. I like all animals so that wasn't a big deal for me and I also wanted to make my boyfriend happy.

After a week since we had adopted the pup, my boyfriend told me that he is sad because the dog clearly likes me more. I told him to not get discouraged because he has tendencies to spiral into negative thoughts. He said that I don't see all of the dog's negative behaviours towards him because I'm not at home as much as he is. It's true, I spend a lot of time at work. My bf kinda blamed me for the fact that the puppy liked me more because I'm way softer than him if it comes to training and eliminating bad behaviours.

Since then, I'm really trying to be less soft and more consistent with the training stuff. I've noticed that the dog indeed likes me more – he follows me everywhere, he is way happier when I come home etc. Meanwhile, my boyfriend is frustrated and sad that his dream didn't come true and keeps complaining that the pup doesn't bring him any happiness and that dog doesn't like him at all (I don't think it's this radical).

I think it might be my fault for being too soft or maybe it's the fact that I'm a totally different person than my boyfriend. I'm quiet, I rarely get nervous or angry, my bf is the opposite.

I'm sad and nervous about the whole situation. I really wish the pup liked my boyfriend more – it was meant to make him happy, not miserable. How can I make the situation better?
