Great song, Jerry. Here's the rest:

1.
I'm looking over my dead dog Rover
Lying on the bathroom floor
One leg is busted, another is sprained
The third got run over by my CocoPuff train
No use explaining the parts remaining
You've seen them all before
That's why I'm looking over my dead dog Rover
Lying on the bathroom floor

2.
I'm looking over my dead dog Rover
That I overran with the mower
One leg is mangled, the other is gone
The third leg is scattered all over the lawn
No use explaining the one remaining
It's stuck to the kitchen door
I'm looking over my dead dog Rover
That I overran with the mower
