Notably, Help is a combat action. Working Together is for other challenges like exploration or social interaction. They mostly work the same; however, Working Together mandates that in order to gain advantage, the assistance must actually be productive. You may therefore decide as DM that sometimes the animal companion can help and other times it does not, depending on the situation.
As well, having a high passive Perception is good, but if you have concerns about that, it may be because of how you use passive Perception. First, to gain the benefits of a high PP, the character must be in certain rank of the marching order (depending on where the thing being noticed is relative to the party) and not performing other traveling tasks unless they are a ranger in favored terrain. They also need a light source or else they take a -5 to their PP if they are relying solely on darkvision.
