What is the Work word?

My hooman mom is using the word work but I don't know what it means.  I don't think I like it though because she doesn't sound happy when she says it.

So far day 1 in my new home has been fun.  We went out lots and I got lots of praises for going to the bathroom outside.  I don't have the heart to tell the hooman that she sounds slightly looney when she does that high pitch squeal but it seems to make her happy so we will let her continue with it.

I took another walk, I chased the hooman and a couple of the furry ones through the house, and chewed my bone for awhile.  I'm feeling sleepy and that doggie bed looks pretty comfy.  Mama says that's where I can stay while she is at the work thing and that's sounds pretty ok to me.

My tummy is very full, we mixed some yummy wet softer food with the bigger kibbles and that was so good that I gobbled up a lot.  Mama seemed to like that.  So far I seem to have this puppy thing down and I think I landed in a good spot.  If only the other furry guys wouldn't look at me like I was an alien.  Doesn't this guy realize that he looks silly?
