Superman has always had a dog, and his name is: Superdog!
Now, you can dress your pet up as the supermost dog in the world! See them leap over obstacles in a single bound! Run faster than a speeding human!
All while having a billowing cloak rustle in the wind behind them! I can only imagine a small statured lady with a large nose and large glasses running behind your superpet screaming, "NO CAPES!"
