mate im assumin theyd get along well. cauz there young, if they grow up with the german shepherd, theyl get use to each other. my mates got a 2yr old pitty and also a 2 yr old shitzu, and they get along fine. just raise it up in a nice manner, and give it the attnetion it needs, and they should be fine. pittys are not as viscious as ppl make them out to be, its ppl wh make them that way.
