Throw away account, mobile, I'm exhausted excuse the mess. On with the issue...

So mid December my boyfriend and I got a puppy, it was his friends, so there's no papers on who's pet, but I paid for her. $200 to be exact. 

We've been fighting alot, and talking about breaking up, he say's he'll take her. Cause his son loves her. 

Well so do I! I feed her, take her outside, buy her toys, clean up her accidents.. he helps occasionally but it's mostly me. And I snuggle her, she loves sleeping with me. She loves them but I feel like she's mine.


SOOO, WIBTA if I chipped my pup without telling my boyfriend claiming rights? (I plan on taking her to the vet next month.) or does that not even how it works. 

Thanks for reading!
