This is the theme song from the movie "Old Yeller" 
 
I used a capo on the third fret to eliminate the G# and D#  
in key change of the song.  The song is in the key of D. 
 
Capo 3rd fret 
 
 
Intro:  harmonizing a capella 
Old Yeller  
Old Yeller 
Old Yeller 
 
Chorus: 
E 
Here Yeller 
 B 
Come back, Yeller 
  B           F#         B 
Best doggone dog in the west 
 
Verse:  
      B 
Old Yeller was a mongrel 
    E 
An ugly, lop-eared mongrel 
  B                          F# 
Fancy free without a family tree 
    B               
But he could up and do it 
      E 
And prove there's nothing to it 
     B            F#             B 
And that's how a good dog should be 
 
Chorus  
E 
Here Yeller

Come back, Yeller 
  B           F#         B

Verse: 
      B 
Old Yeller was a hunter 
    E 
A rearin', tearin' hunter 
    B                             F# 
In any chase he knew just how to run 
     B 
And when he hunted trouble 
     E 
He always found it double 
     B                F#        B 
And that's when Old Yeller had fun 
 
Chorus: 
E 
Here Yeller 
 B 
Come back, Yeller 
  B           F#         B 
Best doggone dog in the west

Verse:  
      C 
Old Yeller was a fighter 
     F 
A rootin', tootin' fighter 
    C                             G 
In any scrap he knew just what to do 
    C   
A rough and ready fellow 
    F 
Although his coat was yellow 
     C           G             C 
His bold Texas heart was true blue 
 
Chorus :
