Are you saying someone broke in and poisoned your dog? I'm reading and I'm getting very sad and very upset. I just didn't understand how the window missing played into this if it was not to say someone messed with your dog and that is truly heartbreaking. I hope you are doing okay (spiritually). Sometimes your pets are like family and your only true companions so that has to be a terrible feeling. I'm glad you have memories to hold close to you. And I hope you never find who did this because I wouldn't want you to put a face to such a horrific person let alone have any type of reaction that might end you up in a situation that you didn't intend (as probably would happen with me, if I found the person that killed my family pet/member).
