Hi, Welcome. I'm new here as well and the people here are awesome. I'm on the Island so quite close to you.
I also just wanted to say I'm sorry you are going through this and hope you will find answers. She's beautiful. I have an almost 15 1/2 year old cockapoo...so I know about old lady stuff (her not me! LOL).
You've come to a very caring and warm place. I hope you will find support and answers as you travel travel this road with your girl.
