My sister's pittie will fight any dog that she decides she doesn't like. She's worse with other female dogs but will definitely attack males; she once jumped out of a car window to attack a male Beagle that barked at her (after this my sister bought a muzzle).
She gets along okay with my dogs (both male) but I think only because she's known them since puppyhood. Otherwise I can't imagine she'd get along with Pongu.
