Well, Tobi's certainly cute but perhaps on another photo, he's not the ugliest one as Cameron said, that's sure ! Could you upload another one to see. If you want and if you can.
I love dogs. And I know that because he's yours you find him more cute than another. I know it ;) But please, don't take this answer in a bad way. Dogs are the best friends of human beings, they're all cute but in a different way to each one of us. But the most important is Tobi's yours, and the look of others isn't important if you love your dog enormously.
Hope you'll understand my answer ! It's a bit complicated in the way I turned it. x)
