I've also started shooting at Reba. With a water gun! After dealing with a scary dog fight between Tessa and Reba I decided I needed some serious artillery. So I invested in a Super Soaker water gun. And it works like a charm! My brother and sister-in-law were up visiting with their puppy this weekend. Reba was her charming rotten self. So I spritzed her every time she looked funny at this puppy, every time she growled or made a negative mover she got sprayed. Fun for me and very effective. Worked well with Tessa too!
Tonight when I was going to work the sheep with Joe, Reba began the awfullest racket. So I sprayed her and magic - no more barking! Love the water gun! She's gotten so all I have to do is pick it up and she'll run into her house and pout.
Now all I need to do is develop some practice with a real gun and do some predator control of my own.
