A Dog's Life?

I found this picture on my mobile phone taken about a week before our son was born. I was busy working up a sweat cleaning and mopping in preparation for the arrival of our bundle of joy and when I felt I needed a break by crashing on the sofa, I found it was occupied by none other than the Jack Russell Duo - who were sound alseep.

Can someone remind me... was the phrase "A dog's life" supposed to be a bad thing??
