I know a dog and his name is Rags 
He ate so much that his tummy sags 
His ears flip-flop and his tail wig wags 
And when he walks he goes zig zag 

Chorus: 

He goes flip-flop wig wag zig zag 
He goes flip-flop wig wag zig zag 
He goes flip-flop wig wag zig zag 
I love Rags and he loves me. 

Chorus Actions: 

Flip flop: hands up beside head as ears, flop one over, then the
other 
Wig wag: wag one hand behind body as a tail 
Zig zag: make a zigzag motion in front of body with both hands 

My dog Rags, he loves to play 
He rolls and he rolls in the mud all day. 
I whistle (whistle) - he doesn't obey 
He just runs the other way
