Fortunately it's latex paint and washes off easily. Of course, I didn't notice how much paint he got on him until he was truly and thoroughly covered; he got both ears, his nose, and both sides of his body. Dogs are always cutest when they've done something to amuse us and they don't understand why we're coo-ing and giggling at them.
Archer was 'helping' me paint. As often happens when a dog helps you paint the dog ends up with more paint on it that the thing you are actually painting.
