Is the temple dog a style of fly - kind of like where the Intruder is heading??
The Temple Dog is a hairwing that grew too big for normal hooks. Honestly, if you just take a piece of arctic fox and mash it on a tube swing it through some choice water you'll get some follows. So when you have this four inch long piece of temple dog swimming through there with some goodies attached, it will generate some curiosity/anger from fish.
What keeps the TD from fouling? The same thing that keeps the intruder from fouling.
A. Make good casts
B. Visualize the fly and how it is swimming through the swing making adjustments
C. Periodically bring the fly in to check on it
