Absolutely gutted for you mate. We had our dog for thirteen years and had to have her put to sleep a few years ago,due to a brain tumour. One of the hardest decisions we have ever had to make but was the right thing to do. She was most definitely part of the family. My son was only 3 when we got her and my youngest daughter was born 5 years later so they new nothing but the dog. She was the best dog we could have ever wished for and I still feel upset to this day. I'm sorry mate,I feel your pain. If dogs could speak I'm sure Lexi would say thank you for giving me a wonderful life and a loving home
