Do you trust your dog?

I do trust Sniper with other dogs at this point in time, as she is only 9 months old, and I know with the pit bull in her, things may change with her feelings towards other dogs as she gets older. At this point in time though, she is excellent with other dogs. She is very playful but not pushy, and she is submissive when she needs to be.  

With people, I don't trust her 100%, especially with men. She is almost perfect with kids, is sometimes a bit shy around women she doesn't know, and is usually quite fearful of men when they first come in (due to lack of socialization of having men come into the house when she was a pup, we are still working very hard on it). After a treat or two, she is best friends with them, but it is the initial growly/slinky reaction she does that I wouldn't trust her 100%.
