I don't think frothing is the right word. It isn't froth or foam, but sticky wads of spit.

The word slobbering comes to mind.

More often used to describe the drooling of a dog but is perfectly acceptable for the picture given.

Slavering - defined as to let saliva run from the mouth

Spittling works as a rare present participle of spittle, most often used to refer to spit when ejecting from the mouth.

Sources: Googling "define spittle" gives the definition, "saliva, especially as ejected from the mouth." I believe Google get their definitions from the Oxford English Dictionary.

We often use the verb:

splutter

... to indicate someone spitting whilst speaking loudly, aggressively or when very emotional. Here's the link to the word in the Google dictionary: spluttering
