I know this subject has been spoke about before but...
When showing my dog when moving him he tends to start snorting (not all the time just occasionally, normally in the first class of the day or when hes excited)... any ideas how i can help him not to do this as it spoils his chances as i have to stop him for a while and calm him down!?!

If you place your hand over his nose and mouth for a few seconds, and he will stop almost immiediately :D
