My Terrier

My dog is a hoot.
She is a terrier.
She sounds like a flute.
My couch has never been hairier.
When she robs a bank, she always gives me the loot.
No dog is merrier.
If there's a problem, she always gets to the root.
Oh, how I love my terrier.

She's low to the ground, and she may be a hound.   I only know that she's a dog, even though she can out-croak any frog.  (She can also balance on a log.)
