quite honestly she looks like my friends lab x collie (smooth) infact she could be my friends dogs littermate.
however id lay bets that this dog has at least 4 or 5 different breeds as part of her genetic makeup if not many more...
while CAROLINA DOG (they are not true dingo) could work, there still relitivly rare, they are not a true 'breed' as such, but a combination of generations of mixed breeding and natural selection between feral dogs in south carolina that have since been brought into breeding programs to 'refine' them as a breed within itself...
she certainly is a cutie though
