Bella is your dog. It doesn't matter that her ex-boyfriend purchased her...You have paid all her expenses (though I don't know how long it's been, but sounds like a while). Think about how much it would have cost your daughter to kennel Bella all that time. She didn't pay for anything for her and thinks she can just come in and demand her back. Time for a life lesson for her, and for you and your husband to teach it to her.
As for her being selfish during your accident, if she was treated like a princess growing up, you shouldn't hold it against her for doing what was taught to her. My niece is the exact same way. My sister thought it was "cute" to say "she's my kid and I spoil her as I want", Well, now she's 17 and doesn't have an ounce of compassion for anyone else. But that's not the kid's fault, IMO. My advise is to change you ways with her now and put that foot down. She'll be angry and say you "stole" her dog, whatever, but when she grows up, she will comeback to you and apologize. the only want she will change is for you stop giving her everything she wants and stop letting her teach you so badly. DON'T let her see that she's hurting you, just be matter of fact in front of her. When she's gone, you can break down if you like.
Bottom line is there is no small claims court around that would say Bella belongs to your daughter, as she didn't hold up her end of the agreement and you've footed all the bills and care (she didn't even pay for your time). Plus, no cop worth their salt would tell you to give her the dog or get arrested for theft as this is not a crime. You haven't stolen Bella, you pay for everything for her, so she's your's.
Do you have to license your dogs in your town? If so, is she in your name there too? IMO you have all the proof of ownership that you need.
Some times being a parent to the skin children really stinks, but it will get better when she finally matures and sees you are right. and that she was being selfish. Good luck and I'll be praying it works out so as not to be a wedge between mother and daughter. So sorry you're going through all this with her. But PLEASE, don't stop paying for her college and insurance. Be the bigger person on that. She is trying to be a responsible person, she could have dropped out of college to play house with this new guy, so reward her for continuing her education. Just my two cents
