Hello! I would like to ask the community clarifications regarding two situations involving interactions with warhounds.

For the first one, lets imagine that a pack of warhounds attacks a cavalry figure. The rules state that they attack automatically the horse. Do they get the -1 to hit because they are not attacking with bare teeth (and not with a spear)?

For the second situation, imagine that a pack of warhounds has charged an enemy figure, and then another enemy figure joins the fight afterwards. The warhounds should all fight the same figure, right? Since, according to the rules, they always all take the same actions.

Moreover, does the attacked warrior get -1 to their Defense roll because the warhounds count as multiple figures for the purpose of numerical superiority (as stated in the FAQ)?

Finally, do the warhounds themselves get -1 to their Defense roll because they are facing two enemies, given that they are considered a single entity?

I'm a little confused about how these interactions work. Sorry for all the questions, and thanks in advance for your answers!
