I've just tried to pick the words out from the Eric Bogle songbook CD for the lines in question.

I am convinced that he sings Irish Labrador.

The next line is difficult to pick out and I can not make sense of what he sings but the way he does the harmony parts, it ends up sounding like "And a woman that is woman passing".

The 4th line is "I kept him on a lead all day and locked him up at night".

Intersting to see that Eric Bogal appears to have slightly different words in his book and CD but I guess a lot of perfomers do that.
