Dogs spawning in villages (like cats spawn)

    I have an idea. Currently in Minecraft there are two types of "cats", we have a wild cat (the ocelot), which has only one type of skin and we also have breed cats, which spawn in villages and have several types of skin. my idea is to add a similar mechanic for the wolves, adding a counterpart of them that spawns in villages, these would be the dogs. Like cats, dogs would have multiple breeds/skin types and could be tamed with bone and would also breed like wolves. Another idea for dogs (and maybe for wolves as well) would be to pick up bones and sticks dropped on the ground and take them to the owner, picking them up in his mouth just like foxes do. Unlike wolves, dogs might not attack hostile mobs (maybe some breeds would attack or they would just try but would do almost no damage) and neither would sheep, but they would bark when they saw one of these mobs. That's my idea, I think its the most vanilla accurate way to add dogs in Minecraft.
