Lockjaw the Boxhound
From Dota 2 Wiki
|Lockjaw the Boxhound|
Most boxhounds you're likely to come across would sooner eat you just for touching them, but all this little guy ever wants to do is play fetch. His master never came home from battle, so if Lockjaw follows you home you should probably keep him.
Lockjaw the Boxhound is a custom courier. It was made for The International 2012.
The courier could only be found in Unusual quality in Treasure Chests, Promo Cards, or as Tournament drops. It drops gold coins as an unusual effect.
