Remember the character in the Peanuts cartoon, Pig Pen? The boy who walked around in a cloud of dirt.
That would be Sunny. He loves to be dirty. After I groom him he finds the nearest dirt hole and rolls until he is covered and disheveled again.
See the resemblance?
I think this is very funny. The last horse we had for almost 20 years loved to be clean. Well, naturally, her name was Fancy Me. She kept her stall and her body clean.
Sunny is all boy.
He likes to look like no one cares.
