It's never stupid to love a pet and to mourn their passing. They are members of your family. Anyone who reads your post and has had a dog will understand completely. I am so sorry for your loss. We lost a wonderful Australian Cattle dog a little over a year ago. Although I have stopped crying, I still think of him and miss him. Maybe, when you are ready, you'll be able to share your life again with a rescue dog who is searching for his forever family....sadly there are so many out there due to foreclosures. Good luck!
