Training their old pet slave in the forest

They want to have fun with him there, but he turns out to be a lame old boring mutt. Again and again, they throw out sticks that Old Grandpa doggy slave, Tomi has to fetch constantly. Totally out of breath, he must then comply with all their commands: make room, make males, fit, etc. But he is simply an old boring useless mutt! And is therefore he will be verbally loudly humiliated by the two young impudent brats all the time verbally insulted and spit.
