In our limited play yard space, we have several things for the dogs to jump on, go through and hop on.  No fancy stuff here!  One is a cement culvert that Kassie  loves to hop on and sit pretty on.  I think she looks like she is waiting for someone to come and adopt her!  Kassie is wonderful girl who has a small blue spot in both eyes.  Call to see her or come out on Saturday afternoon from 1 to 4 when we are open for adoptions.
