Looks fine from here.

For the jungle hounds, should infallible tracking be modified for scent in addition to (or instead of) sight?
7 days is superlong compared to the 30 minutes we gave the jann saluqi to track by sight. Normally, the DC for tracking by scent goes up by 2 per hour as opposed to 1 per day for tracking by sight. If anything, I'd reverse the numbers!
How about 7 days for the normal jann saluqi and 4 hours for the jungle version?
If we're going to do that, I want to say that the sight-tracking jann saluqi have +0 DC per day later. These special abilities should make sense in the context of the general rules.
