and i thought moondoggie was smart & talented! have you heard about the doggie da vincis . . . three service-trained dogs who have learned to express themselves through abstract painting. sammy, a foxhound mix, uses a paintbrush attached to a rubber bone to create bright strokes across white canvases. signed with a black paw print in the corner, original work can go for as much as $350. i wonder if sammy would give me some private lessons.
