Sorry to hear that Wook. Well, I know there's no "replacing" pets but my advice would be to give urself some time to morn then start a new relationship with a new dog(or two new dogs).
Life is brimming all around you my friend and there's many pets that would love your home and your companionship.
Btw, my daughter's cat is very old and she's super attached to it. When it does pass, I'm gonna bring her a new kitten. I already know my daughter will have mixed emotions but I also know her heart will melt and she will immediately take to it. It's the circle of life. For all its pains there's a beauty to it too. New beginnings, new bonds, a new chapter. In time youll be okay again. God Bless 🙏
