Here's a few near my zipcode that look fairly similar.  I know some of these are crosses, but we don't know that the OP dog isn't a cross. 

Mastiff,
Out of all of those I think OP's dog resembles the Pitbull/American bulldog mix.
Like I had originally suggested.
But she looks an awful lot like an dogo, too.
To someone who doesn't know better, all dogs considered look pretty much alike.

She looks alot like a Dogo in my opinion as well, but before telling the city authorities that, I would make sure there were no breed specific ordinences on the horizon. Maybe claim her to be a Dalmation mix, or Boxer mix. In the past, while working at a vet clinic, we had to go to bat for one of our clients that had a Boxer/Labrador mix. We knew the litter he came from, and the sire and dam, but the city police said he was a "pit bull"!  The owner's insurance company wanted to cancel  their home owners policy, and the police  were convinced he was dangerous! He was a gentle dog with a big bark, and the meter reader had left the gate open, so he got in the front yard and was barking at folks. It all ended well because the vet was able to find the owners of the mother dog and several people swore he was a Boxer/Lab.

ORIGINAL: dstull

The registration of a dog at any time in any jurisdiction as a pit bull or any of the dogs listed above shall constitute prima facie eveidence the animal is prohibited by this section."

Kara Ann has a Dogo named Gracie.

I'd say she looks a lot like a Dogo as well...and yeah, it'd be rare to find one in an animal shelter, but then again I was at my local animal shelter a few months ago and they had a purebred Cane Corso there for adoption...I saw the sign and doubted it was a pure, but when I saw the actual dog all that doubt dissipated instantly.  That was one heck of a gorgeous dog...definitely looked pure to me!
