Let your pooch become a prehistoric beast with this dinosaur costume! He’ll be able to stomp around where ever he wants, which is the primary benefit of being a gigantic man-eating beast. If you have a little pup they may not be so convincing as a T-Rex, but the rest of the world will have a good laugh as he tries to roar and chase his own dinosaur tail. A future Youtube hit with a million views? With this pet costume, we think it’s totally possible.
