Dog sitting....a surprising fit

So, my boys have been hounding us to get them a dog.  So we are dog sitting this week and have a nice 10 year old dog staying with us.  It has been easier than I thought or this was the case when I started this post.  Four days in it is still going pretty well, but the boys are not eager to pick up droppings or always at the ready to let the dog out.  So while the dog seems to be fitting in better than I thought, my boys are getting a taste of what it is like to have a dog 24/7.  I think we will get a dog in the near future, but not sure we are quite ready.
