And I'm pretty sure it's "If they could speak, they'd tell you why."

Here, I'm pretty sure, are the lyrics as sung by the Lizards. (I'm guessing one or more of the Lizards also wrote it, but I don't know for sure.)T

THE DOGS, THEY REALLY MISS YOU
As sung by the Austin Lounge Lizards

I know the day you left you said, "Let's never talk again,"
But I'm not calling for myself; I'm calling for them.
Our little ones who wait at home are broken and upset,
And though they don't remember much, they can't seem to forget.

The dogs, they really miss you; they're diff'rent since you said goodbye.
They brood; they pout; they feel put out. If they could speak, they'd tell you why.
They're too down to play around; they hardly touch their meals.
The dogs, they really miss you, and I know just how they feel.

Their tails don't wag; their hearts won't heal; they blame themselves that you're astray.
They're sorry that you felt tied down and never learned to stay.
Molly's nose is warm and dry since she sat and watched you pack.
She figures that you must be lost and can't find your way back.

And Scooter's just a basket case; he won't accept my calls.
His squeaky toy lies silent; he's lost interest in his balls.

The dogs, they really miss you; they're not themselves since you're not here.
They sleep all day, watch TV all night; they drink way too much beer.
They've seen "Old Yeller" forty times; they bathe less than they should.
The dogs, they've stopped their poker game, hoping you'll come home for good.

You know how they hate to beg, but the dogs are really blue.
The dogs, they really miss you, and you know that I do too.
Wah, wah , wah- ooooooohhhh!
