Ugh, yes, they do. This is what I get for using too many servals - I keep crossbreeding the two in my mind.
Charge using the AC first, and have the others fill in with the single slam attack they get at the end of the charge. Changes the damage slightly (adds +2 damage), but not the attack rolls. Those that can't charge, just double move into range of the wolves - they'll take AoOs, but with the DR, they should shrug most of it off.
The SDA spells only using animals and then taking away all of their special attacks is going to be really quite annoying over time
