Kilayim 8:6, in listing various animals and whether they are considered wild or domesticated, says:
כלב מין חיה
A dog is a type of wild animal
Why is this? We’re not talking about wild dogs or wolves - just ordinary dogs. Why are they not considered domesticated?
(I should note that R’ Meir argues with the Tanna Kamma. I am asking specifically on the Tanna Kamma’s opinion.)
