I recently had to put down my 15 year old greyhound. I am so sad and cannot seem to get over this. He had been declining for months and I knocked myself out trying to help him. We had him for 12 and a half years and he was such a part of our lives. When the vet came to put him to sleep, my husband and I cried like babies. All of the stress had caught up with me now and I can't seem to decompress. I hurt like crazy and am exhausted. I haven't slept well in about 6 months ( I was always listening for my dog, in case he needed to go out). Any ideas?
