I have three dogs and two of them are still pretty young but the oldest dog is mine. He’s not an old dog, he’s only about 7 or 8 years old but his breed’s lifespan is about 12-15 years and I fear the years getting closer to that. This anxiety came from one of my previous dogs dying. Since then there have been days where I start thinking about when he’s gonna die. I know one day it’ll happen but I know it’ll still hurt when the day comes.
