My name is Elsa!

In the past six months Elsa has been aggressive to our other dog. Causing a broken jaw to our smaller dog and has caused excessive bleeding a number of times. We have considered putting her down but feel guilty doing so. It’s a very hard situation for us. She had her eye removed back in April and since then has been different. She was diagnosed with Cushing disease and we are afraid she will attack our small grandchildren. Don’t know what to do. Is rehoming even an option? We just can’t have her randomly attacking our other pet.
