#spr1 "./Worthy_Heroes/Dogfriend.tga"
#spr2 "./Worthy_Heroes/Dogfriend2.tga"

These two lines give the unit it's sprite, and cause the problem. If you are using Linux, it might be that the actual files have small 'd's instead of 'D's. Any way, if you remove these lines and add line

#copyspr 848

, the unit will have the sprite of Sidhe Lord (unit number 848). That should fix the problem.
