Not sure if these are the full lyrics, but I’m gonna give it a shot from memory..
(parentheses for unsure lyrics)
WATCHDOG IN THE NIGHT

Watch dog in the night
I never chained you
Watchdog in the night
I always trained you
To protect my lovely home
Until the night was through.

When the burglars came
You didn’t mind it
They were after loot
You helped them find it
(All my jewels and furs)
You quickly led them to.

(I don’t remember the bridge, but I remember the rest.)

When I returned to my home
How your jaws did foam
You became a snapping dog
A crazy fearless yapping dog.

Whenever I’m in sight
It’s so upsetting
Every time you bite
It’s me you’re getting

Now you’re full of fight
My watchdog in the night.
