I used to use something similar for training. Its called Roll Over (I think only available in Canada) and also came in big rolls like that. I would pre cut it into small pieces and freeze it in a zip lock bag. I'd take out what I needed a few hours before I needed it.
It was very convenient and lasted a very long time
I didn't know it was going to be as big as it was! Unless he gets bored with them then I won't have to buy Smudge training treats for ages!
