My coty is best friends with all 30 certified service dog pit biulls i know. the pit bulls range in age from 4 to 6. my other two dachshunds adore them too although they dont get to see them as often because only coty is a service dog and a member of our state service dog group that holds meetups where all the service dogs take restaurants or theme parks or other frequenntly visited public places by storm. we have over 300 service dog/handlers inthe group. the largest group to ever go to a meetup was 75 service dog/handlers.
