Batch rename raster images

I have a folder with images named Dog1, Dog2, Dog3, etc. and NoDog1, NoDog2, NoDog3, etc. in the same folder.

I have a MicroStation file set up with about 40 just 'Dog' named images, and I want to change all of them to pull instead the 'NoDog' named images that were stored in the same folder. Is there anyway to batch edit raster image file names/paths like this? My current system is to individually edit the File Names.
