Lay Dutching no 2º, 3º e 4º favoritos em corridas de cavalos com o green-up

Is it possible to adapt this trigger for greyhound racing?

No, because these triggers place some of the bets In-Play, whereas Greyhound markets are closed for In-Play betting.

Ok, so i would like to dutch on lay in a selection of greyhounds. Is it possible?

Yes, it is possible to make lay Dutching bets on selected Greyhounds.

You can use the Dutch Lay trigger action to do this.
