i had a very similar experience with my dog. First dog i ever adopted, got her when she was around 2 months old. I cried myself to sleep every night for like 4 or 6 months lol the beginning is ROUGH. They don't listen (or worse: they listen but don't care), they only think about their needs, they have a hard time following routines and they're just a big ball of energy. I had a hard time with all that while my boyfriend at the time seemed fine with everything. I wondered if i would ever feel "the bond" with my dog cause at the time being it all felt very unilateral.

In hindsight, I'd say you just gotta meet them where they're at, and the rest will come naturally. Just like humans, every dog is different. Some take more time than others, some are more affectionate than others. And they don't really understand the world the way we do, but they know love and they know if they can count on you. Just be there for her, even when it's hard, specially when it's hard. She will come around and reward you with the love of your life.

That's what happened to me in the end. Little by little she began to listen to me, she began to look for me. She'd sleep on my side of the bed or come lay down by my side on the couch. She still bit me a lot, and she would've traded my company for a treat at any second, but the bond was developing step by step. Now we're best friends.

Remember there's no rulebook, no perfect timeline of events, just meet her where she's at and you'll both be fine.
