i bet she could be trained to...but no. i want my friend to paint a picture of my dog, and he knows pooh, and i gave him some good pics of her and bought him a canvas like almost 2 years ago.
i think i'm going to have to commission another artist.
Meh... cheapest method take a High quality digital picture of your dog, parse the picture through a "paint stroke" filter of a paint program like photoshop, paintshop or of course GIMP. This will give you a huge picture that looks like someone painted a picture of your dog. You should then be able to take it to a printing shop and have it printed huge enough to be framed.
Alternatively you could do some sort of "amateur" painting contest, get a picture of your dog like before and stick it online on a website offer some sort of reward as a prize and get people online to submit their works (either electronically or by post) of course you'll probably have a bunch of kids send you their interpretation of what your dog looks like (priceless).
