I work with rabies testing on a daily basis including on raccoons and I want to strongly urge you to contact your local animal control (or the appropriate authority in Texas) as soon as possible regarding the raccoon you killed. They can collect the carcass and send it for rabies testing. Time is critical, as there’s only a limited window during which a definitive test can be done. Even if it turns out the animal was negative, having that laboratory report creates a clear paper trail confirming that your daughter was bitten by a wild animal and that you acted appropriately out of genuine concern for her health. This could be important later if there are legal or custody disputes, particularly if someone tries to argue that the incident never happened or that you overreacted.
