Well, it is true that an abscess can be life-threatening as well as painful. But given her history of scam and scum, the donation for the pulling would only be "safe" if: done on an in-kind basis rather than donating $$; with TTW sedated into unconsciousness; video "taped" from multiple angles so as to preclude claims of sexual or other physical abuse.
I doubt TTW would go with those conditions, but she is what she's made herself - a used up skank with a needle-free moral compass; unemployable; a scamster; irrational; potentially violent.
I've seen "homeless" people (or professional panhandlers) with dogs better behaved than TTW's apparently is.
