If i wild shape into a creature who's attacks cause bleed, does wild shape give you that ability. I think the real rules question is that if bleed is an ability that was omitted or was one that was assumed. Like it isn't a special attack or something that would be listed. I'm leaning towards bleed not included but that seems weird because it isn't super strong or anything and is kinda common. It feels like something they should get but i don't think they do.
The Wild Shape functions like Beast Shape 1 or advanced based on level.
Beast shape 1 provides a list of abilities it can imitate: "When you cast this spell, you can assume the form of any Small or Medium creature of the animal type. If the form you assume has any of the following abilities, you gain the listed ability: climb 30 feet, fly 30 feet (average maneuverability), swim 30 feet, darkvision 60 feet, low-light vision, and scent."
The better the beast shape spell, the longer the list of things you can do - but Bleed is not on any of them. So, by RAW (and RAI I think), No, you cannot.
