I'm sad now
My condolences. The positive aspect is that you have time to prepare yourself for it, and be there till it's done. My family lost our cat suddenly, when I was in grade 11, and I was the one to find her on the sideway *sniff*. We had her since I was 3, so she was a member of our family. To this day, my family hasn't been able to get another cat. Oh, and definitely take and collect some photos of your dog. If there is one regret, we wish we had more pictures of our cat when she was still alive.
