Suki and I had our first dog obedience class tonight. My perfect Suki was behaving aggressively towards the other dogs. I was shocked! So the instructors gave me a water bottle to spray on her when she would lunge at other dogs or growl. It really worked, thank goodness. She does all the commands perfectly though, not that I can take much credit for that. She knew, heel, sit, quiet, and down when I adopted her.
I was hoping that the class would wear her out a bit, but I'm the exhausted one and she's still playing with her toys. lol.
