Sorry for your loss. It can be crushing. Other will share their experiences to try to help by saying you're not alone. Please consider adopting an adult dog. Everyone goes in looking for a young dog and the oldest dogs get passed over.
Sorry to hear. Had to do that a couple months ago. Very few things to compare. My daughter just adopted a 5+ year old Pyrenees from shelter today. Have been looking at pics and video all day. He is so happy to have a forever home. Something to think about when you’re ready.
Craig, check these people out. I didn't read what the whole stick is but it might work for ya.https://muttville.org/seniors_for_seniors
