IMO use anything your dog responds to and only use it during training times so eventually they know what time it is and what they've got to do to get what they want , it could be a squeeky toy , ball or treat as long as they know they have to work for it as a reward
Chopped up cooked chicken breast is a good one dice it into small cubes and take some out with you when its walk/training times
But make sure whatever you decide to use only comes out during training and only given once command has been followed
When's the new arrival landing anyway mate ?
