For his costume, I decided to forgo an actual doggie one. I just got a pair of kids pajamas that were on sale at Target for $8.00. Can't beat that price!
I cut the sleeves off of the top and didn't bother with uncomfortable pants since his legs are black anyway. The pajama set even came with a blue cape that velcro-ed onto the back!
And voila! You have completed making your handsome Batman dog.
And this is my sorry effort at Poison Ivy!
