Luke seems to be doing ok at dog school but there is always a hesitation when given a command to to something.

It usually goes like this..command....pause..... then sometimes he does it and sometimes not.

Several thoughts that may be going through his head...

I know what you want but what's wrong with what I am doing now?
I'm not going to drop, the grass is wet and cold!
If I do it, what's in it for me?
