Late last night Dax started to cough, really hard. Usually coughing about 3 or 4 times and then gagging. Today he is still coughing a little bit and threw up a little foam. He was at the river yesterday evening, could he have inhaled some water?

I suppose it's possible he inhaled water. But the way you describe it sounds like kennel cough. It's a very distinctive cough, sounds like they are trying to bring up a hair ball or something and often ends with throwing up a little foamy mucus. I would call the vet. Usually antibiotics are given and otherwise healthy dogs get through it just fine.
