Earlier tonight I found what turned out to be a fun little game. It's called Shepherd Farm. 
In it, you play as a border collie and herd sheep into a pen to be shorn by a shearer. When they're done, the shearer releases them and they go back out into the paddock where their fleeces regrow and you can herd them again.
The fleeces stack up and you use the dog to gather them, take them to the top of the area and sell them to waiting customers. With the money you buy more land areas which provide more sheep.

To help with the game you can either use game coins to buy upgrades and helpers, or you can watch adverts. 

Also, there are wolves to bark at to scare away from your flock!

The graphics are great and there's no annoying music. 

AND THE DOG'S TAIL WAGS AND ITS EARS FLOP UP AND DOWN AS IT RUNS!
