Animal Companion Abilities and "Con Based DC"

[DeathMetal4tw]

I just don't get what this means- I see a lot of creatures who's special abilities simply say "Con Based DC"- Take the giant spider's poison for example. I don't know what this means and I can't see an explanation anywhere.

Is the DC something like 10+the animal's con modifier or something?

You have the gist of it.

I believe its 10+hd+con so if you get your spider a belt that boost con the DC would go up.

DC 10 + 1/2 racial HD + Con modifier.
