The Max Hunter Folk Song Collection has a version very close to the one posted by Guest, 16 June 03.
Sung by Everett Griggs, Clinton, AK, 1975, it can be heard in RealAudio at: Here, Rattler

Chorus:
Here Rattler, here
Here Rattler, here
Ole rattler's bound t' bark
Here Rattler, here.

Grandad had an ole blind dog
As blind as he could be
Every night at supper time
You'd think that dog could see.

Ole rattler, treed th' other night
I thought he'd treed a coon
N' when I come t' find out
He's a barkin' at the moon.

Grandad had a muley cow
She's muley when she's born
Took a jaybird forty years
To fly from horn t' horn.

I wonder how the ole blind dog would know the moon was out?
