I've created a 9th level Druid with a Riding Dog companion. I've
encountered two problems with the companion's Feats:
1) I'm not sure how the feat selection is supposed to work out
exactly; i'd think that it would automatically assign Track and
Alertness and leave me with two feat slots to choose from (from hit
die 3 and 6), but instead it seems to be assigning no feats
automatically and giving me only three feat slots to choose.
2) I seem to be unable to select Improved Natural Attack for the
riding dog. I may simply be doing something wrong, but I suspect it
has something to do with the PREITEM tag, as that is the requirement
that is 'redded out' in the information pane for the feat.
