The meaning of the idiom, it’s a dog’s life, means that life is hard an unpleasant. I am not sure if that still valid nowadays?
I’ve been working very hard these days, came home late, and need some time to chill, but on the other hand, I still would like to get some of my work done. So, instead of chilling at home, maybe ended up working night time at home as well.
Looking at the life of our dogs, who said that they are having a tough life? I would love to live their life! They just eat, play and sleep, then eat again, play again and sleep again… What can you ask for more?
I definitely need some sleep now……
