Oh yes, I am the same way, Mac. Also I just think about the other animals too. Animals are smart. They also grieve. I know it hits the coop hard after a death of a chicken. I've had three die within a year and I was trying to convince my mom to let me get chicks or let my hens hatch their own but she said no lol.
my dog was put down last year, it's hard, i know. But you can't grieve forever, take a little while and it will get easier, when you feel ready, get another dog of a different breed, that way it doesn't feel as though you are replacing her, it feels you are just adding a new dog to the family <3
That and when we had two dogs - one died of old age, and the other went into a deep depression. He ended up getting cancer and we had to put him down, but he was so unhappy. I think if we would've gotten him a new friend he might've at least lived his last days super excited about a new friend.
When our dog died we unexpectedly got a rescue dog. We thought we weren't ready for another dog, but if we didn't take him he'd have been put down. He's a great dog now and saving him gave meaning to losing to first one.
