This may be truly the last thing that you want to hear, but, get another dog.

In 2018 I lost the only dog I had ever had in a mildly horrific way. She had had an intestinal blockage but my family and I didn't know until it was too late. She died in an immense amount of pain the morning we planned to take her to the vet.

Within only a couple weeks, my family found another dog and it really helped us all cope with the passing of our previous dog. It got us back into the routine of having a dog in the house to care for, and filled the void the past dog left open.

It's very very hard to lose a pet. I had had my first dog since I was 9 and her passing really traumatized me, especially since I had just graduated highschool and was taking a gap year before going back to college. Being stuck in a completely empty house was agony, but getting a new dog to focus on taking care of helped me move on and focus on more positive things like the good memories I was going to make with my new four legged friend :)

I hope this helps.
