Crash Said,
Costello was going for atmosphere above narrative. He often indulged in what a critic called "image mongering," dropping in a vivid image or a clever play on words
Exactly! Almost all songwriters do this. Dylan being the best-known current example.
But the words, plus the melody are designed to send a message to both your head and your toes.
I scoured the net and even my old copy of the Shorter OED without finding a meaning for "dogs" that fits the lyrics
Crash, you are trying too hard to find something obscure. That way madness lies.
Paul McCarthy is dead! And guys! Please don't start!
One thing McManus was, was an observer. And he was using his eyes and soaking in what he saw in '77. And believe me, there was a lot to see.
In order,
'Nice girls, not one with a defect' - when he was on stage - he would see girls in the audience dressed up to the nines.
'Not one with a defect' in the context of the whole lyric, this is sarcasm.
'Cellophane, shrink-wrapped '
Dresses that were tight and plastic - Take a look at Fay from the Rezillos for example.
'So correct' more sarcasm. McManus was observant and critical of fashion in more than one song.
'Red Dogs under illegal legs' - obviously red shoes. Poetic license. Under legs are feet, which have shoes on them. Red Shoes were also very fashionable at the time.

How did the word ‘dogs’ come to mean ‘feet’? In 1913, a journalist for the New York Evening, by the name of “T.A. Dorgan”, was well known for rhyming slang, published the word ‘dogs’ as a citation for his feet. From that point forward the word ‘dogs’, has been used as slang for feet.
'illegal' shouldn't be taken to mean anything other than that the girl looked very young.
Everything here is
visual description.
Then in order,
'She looks so good that he gets down and begs' Visual image again.
BUT!
'She's watching the detectives!'
Can't see how that can be anything but literal. That sets the stage for the narrative.
So now we have the picture of the frustrated guy and the rest of the lyric has a double meaning.
Sarcasm all the way!
And yes, 'Shoot! Shoot! Shoot!' has an obvious double meaning! but it's funny. Emphasizes his frustration.
In fact it has a triple meaning!
Now baby's here to stay, love is here for a visit They call it instant justice when it's past the legal limit
The detectives come to check if you belong to the parents - Who are ready to hear the worst about their daughter's disappearance.
It only took my little fingers to blow you away
It's hard not to argue that that doesn't indicate that 'she' is underage and again he is using lyrics that apply to the Detective show, with double meanings, to imply something else.
'It only took my little fingers to blow you away' That is deliberately obscure, could be interpreted many ways and the meaning is in the mind of the beholder Mistake to look for a definitive meaning. It's a simile.
I'm not going to outline my interpretation in this space.
And then, 'Watching the defectives!' and we are out!
I'm uncomfortable with this kind of analysis which can be turned against a person.
We live in an age where someone writes a tweet or message, millions read it and make assumptions and a person is judged and their life destroyed. Only takes one person with an Axe to Grind.
Get a 'good' lawyer and there is money to be made.
Anyway,
My review of the books coming up on the weekend.
Cheers!
