Raleigh is already showing signs of DA. You must never leave them unsupervised and be prepared that one day the “swatter” may not work. I suggest crate n rotate. It is hard at first but you get used to it. It’s safer for everyone. I thought the same way as you did a few month’s ago until I couldn’t stop it. One dog was at one end of a very large yard and the other was playing with a ball at the other end and one of my dogs ended up with a hole in his shoulder, stitches and a hefty vet bill as well as a long tedious recovery. Invest in a break stick, only to be used on pibbles. Read up on crate n rotate, multi dog homes at http://www.pbrc.net. Get the animals spayed/neutered if not already. I hope this helps you.
