I need to build one that can be used outdoors.

Where can I find the schematics for this kind of circuits?

Before you try a complex diy solution you already have tried a easy solution, like "Animation away" from "Royal Gardeneer" or similar gadgets which create a ultrasound siren?!? And if this 20,- EUR/USD Gadget is not working for these dogs, you could open it and use 99% of the device to add an mp3-circuit-board.
