After a week of spying I learned the dogs' routine.
Barbie's is as follows:
8.30am - 12.30pm - sleep on the dog bed, with occasional leg stretching and roaching
12.30pm - 2.00pm - move to the couch for more sleep
2.00pm approximately - get up and get a drink, look out the window, dig at the carpet a little, scratch
2.10pm - 4.30pm - sleep on the dog bed
4.30pm - lie in the window to watch for my return
Bender's goes like this:
8.30 - 1.30pm - sleep on the couch
1.30pm - 2.00pm - move to the sun spot by the door
2.00pm - drink, maybe bark at someone outside
2.00pm - 5pm - sleep on the couch
I find it interesting that Bender hardly barks during the week. He barks when I am home and people are in the driveway, so maybe it is for my benefit?
