My deepest, sincerest condolences. This happened to me six years ago, so I know your pain. Once it wears off, I urge you to do what I did and get another dog. My new one is a Great Dane and he’s a God send.
My wife got me a dachshund for her birthday last year. She brought him home and he ran to me like he had known me all his life. It’s the weirdest thing I have ever seen. It was like he must have thought I was his owner before he went to the rescue place and finally ended up at my house. He follows me everywhere, kitchen and bathroom, loves to go bye-bye, has beds in every room in the house. It’s pretty satisfying and awe-inspiring. Dogs are a gift from God.
