Hi all,

I came across this game in a practice test (# unknown) recently. I am wondering how best to approach it. I am especially interested in understanding how to diagram this game. Thanks in advance!

Two friends, Rachel and Teresa, own a dog walking business. During a particular week, on Monday through Friday, they walk three dogs--a Newfoundland, and Otterhound, and a Poodle--in accordance with the following conditions:

-Each dog is walked exactly once by each friend and no dog is walked twice in one day.
-Rachel walks the Newfoundland at some time in the week before she walks the Poodle.
-Rachel walks the Poodle earlier in the week than Teresa does.
-Teresa walks the Otterhound earlier in the week than Rachel does.
-Rachel walks the Newfoundland on the day immediately before the day or the day immediately after the day on which Teresa walks the Newfoundland.
-Rachel walks no dogs on Wednesday.
