Hi E.,
It really sounds like your dog is aggressive due to her pain. I completely agree with trying to find her a place where she could be taken care of and not worrying about her hurting your family. I think it's so great that you've considered what would be best for everyone. So many would have just gotten rid of her without making sure she had proper care. I am the official animal lover in our family and I have a really hard time getting rid of anything. In fact, I have rarely given anything away. I did have a similar situation with a different type of animal and I thought we could provide a great home for him. It wouldn't be perfect, but it would be way better than lots of places. My husband convinced me that we needed to find him a new home because I was very pregnant and he didn't want our baby to get hurt. It turns out that the home he got was amazing. He ended up with some truly amazing individuals that are still taking superior care of him and have much more time to spend with him than we did.
I think when we put them first and do what's best things work out for a reason. She needs someone who can give her what she needs, and that may be more individualized attention. We get so busy with our families that sometimes our animals get put on the back burner unintentionally. Her health issues really need to be top priority for her so she does not have the pain.
I really wish I was of more help, but I think you are definitely on the right track.
Have a great one!
A.
