My name is Bella!

I inherited Bella 7 months ago when a neighbor decided after 3 days he couldn't keep her or her brother. I thought I could Foster Bella and find her a really good home. I already have a dog that is 5 years old and is a female. I introduced them and they got along pretty well but as the months went by the older dog started to not like the puppy. Their fights escalated to a point of the big dog wanting to literally kill the puppy grabbing her by the neck and her ears. I really love Bella and it makes me sad to have to rehome her but I know it is for the best for her because the older dog is not going to accept her. I've spoken to a trainer who agreed that I should rehome the puppy. At this point I have muzzles on both of them but they can still drink/eat but I don't feel like that is appropriate for them to live that way. Bella is so sweet, smart, listens to me and loves to cuddle. She's mostly an indoor dog but I feel she would enjoy being outdoors. She just needs human affection too.
