Thump, Thump, Thump

What’s that sound?   Thump, thump, thump.   There it goes again!  Thump, thump, thump.  Oh, it’s Sadie.  She’s lying on the couch and every time that Wen walks by her, Sadie wags her tail and it makes a thumping sound on the couch.  Thump, thump, thump, thump, thump.  Obviously, Sadie is a happy Scottie!
