Can anybody help sort of identify breed?

i have a lovely gal named ruby! she is a pitbull mix i think lol. the shelter people i got her from said she was a little of this a little of that with no definitive answer and then the vet paper work they gave me said pitbull/ shepherd mix. im skeptical about the shepherd part. she has always had some spots but as she grows up is getting more spotty so possibly a dalmation? idk, i don't care really to be honest but it would be nice to say something to get around bsl lol thanks for any input
