Masha is a bear that is chained up every day so hunting dogs can attack her to toughen them up.
“Once the dogs are finished attacking Masha for the day, the exhausted bear is returned to a tiny wire cage, just two feet by three feet. She is given little food and water, to ensure that she is weakened for the next days assault.”
Four Paws are trying to rescue her and will file a lawsuit against the owners (so they cannot just buy another one once she is rescued), but they need donations. You can read more about Masha and Four Paws here
Not tattoo-related, but important.
