Tinker was Theresa's family dog, appearing in the Kingdom Come: Deliverance DLC A Woman's Lot.
He lived at Skalitz Mill with Theresa's father, the Miller of Skalitz, as well as her two brothers Stibor and Samuel.
Tinker accompanied Theresa before, during and after the sack of Skalitz, including helping her find items to try and heal her wounded younger brother Samuel, and locating survivors following the raid. On their return to the ruins of Skalitz, he was killed by a member of Runt's gang.
