Try to carry treats with you so you can reward him directly after. Shelties ARE smart, but with dogs there is a short window period where the treat is connected to the action they did.
I attached a pencil bag to Oberon's leash that I keep filled with treats. That way I always have treats near at hand when needed, even if I forget to put some in my pocket or if what I'm wearing doesn't have pockets.
