The DACA sees the need for US Dogo owners to have ways to keep the correct instincts alive and sharp in their dogs. Obviously the animal rights activist would go 'postal' on us if we include anything 'for fun' that would potentially harm or in anyway stress out a live pig. So, we're faced with alternate 'bait'. More on this later, watch for details soon. Okay, with that said, let's take your questions one at a time.
Conditioning is first and foremost.
The Dogo should be able to run for miles in rugged terrain and still have energy for quick burst of speed to overcome and capture large prey. Start a running ritual and get the dogs in top shape. Otherwise they are in danger when on the trail. A tired dog is a venerable dog. Later you will need to work on scenting.
