Poor Dixie! Unfortunately, by law we are not permitted to give any specific dosing recommendations without an exam - but I can tell you that doxycycline is not likely to be helpful in this case, since the coughing is due to airway irritation from the smoke rather than a bacterial infection.

If she seems to be breathing okay and acting normal otherwise, you can try bringing her into the bathroom with you with the door closed while you take a hot shower - the steam and humidity often help to soothe irritation and relieve symptoms in cases like this. You can also try giving her a small amount of honey several times a day to help soothe her throat.

If there is no improvement by tomorrow morning, I would recommend taking her to the vet for an exam - she may need prescription anti-inflammatory medication or cough suppressants to treat the cough.
