My pup went so quickly it was crazy...she looked every day of her 16 years, but until the last two months, was her normal self. Seemed so long at the time, as I was sleeping in the basement with her so she didn't fall down the steps, etc.
But even crazier was the relapses back to health. We had two or three separate decisions that her end was near and were scheduling her final vet visit, only for her to wake up seemingly 100% the morning of. Brutal whirlwind as I think I had to make peace with things all over again, but having her back briefly was so nice. She ultimately passed away in our backyard, right next to me as she kind of just faded away. It was really beautiful...not in pain or suffering as near as I could tell, and I was with her to the end.
Now resetting the "Number of days since your cried about your dead dog" back to zero.
