Just a suggestion listen to it without watching her perform first to enjoy it best. It's such a GREAT song. Like the best of any of the greats Lehrer, Silverstein, Mel Brookes. AWESOME writing and singing.
I truly love all breeds of dogs - that being said...some sorts of affection between pets and owners leaves me...phlegmatic.
Incredibly-talented Susan Werner nailed one of MY personal pet-peeves (in both senses of the term) in "Dog". She raises all of the relevant points.
The other is when owners speak fecklessly to misbehaving pets as if they are human beings. People, just don't!! Dogs are not human beings (one of their endearing qualities), so they probably understand maybe every tenth word in the human vocabulary. Except of course dachshunds, who understand everything and everything else.
