Well, fire. Like you get poked with the tip of an ice pick that has been over a flame.
Cow Killer Ant or Velvet Ant
The fire ant will bite you, leaving a bad rash or sore which is very itchy. This is where they get the name 'Fire Ant'.
An ant does not have the ability to make a bite twice as painful. The ant may actually bite twice which makes the bite feel more painful.

No, because once you have received the shot, the pain is gone. A red ant bite keeps on stinging for some time.
The pain is due to the formic acid in the ant's bite.

The appearance of the bite would depend on the type of ant. Whatever the any the bite would look very similar to what it would look like on you unless the dog had a reaction which caused excess swelling at the bite site.
It is said it will stop the pain from fire ant bites. Never had a fire ant bite but it does not work on mosquito or blackfly bites.
How long it takes to heal a fire ant bite depends on the person and where the ant bit them. A drug store can sell someone medicine to help heal the bites faster.
There isn't a "chemical name of ant bite". An ant bite is an event, not a compound.
