What anime/manga are the sword and the dog in this image from? I can figure the rest of this image out, but I just don't know what anime/manga the sword and the dog are from. Can someone help me out?
The dog is a smaller version of Sadaharu from Gintama

The colour of the dog is of course Pikachu.

The sword is the Shikai form of Zangetsu, Ichigo's sword from Bleach.
