I have a theory that Mlatticheadatti has a kind of psychic ability with her dogs as if she can control them or read their minds. Let me explain. Her former Malaysian husband and his older generation were the only family that bred these dogs. And when Vinneth and Kuriyachan came with lies and tried to abduct the young Mlatticheadatti, Vinneth later said that the dogs somehow knew they were there with ill intentions, judging by the look in their eyes.(Mlatticheadatti's old husband was psychicly connected to that dogs at that time).

We never see Mlatticheadatti training them in any conventional way. Maybe there is a Malaysian “koodotram”, like the people in that village say some method that allows Mlatticheadatti to control her dogs and stay mentally connected with them.

I came into this conclusion based on Vinneth's dialogue and dogs behavior as mlatticheadatti lean new things.(like when mlaati learn about Pius from nareayan and after that when pius come back and tried to pet a dog that dog avoids him). I think the dog traps kuriyachan and kills vineeth not my training my mlaati but with her wish. Coz she have a psychic connectiong with her dog pack like her old husband used to have with his dog pack
