Ok, I need help with nipping this issue in the bud before the bud blooms into something ugly. Angel and I were walking today, but the whole walk seemed off. From pulling constantly, to lunging, this walk was a disaster almost from the get-go. I have no idea why. But what concerns me is the fact that she lunged, growling, at two different men, both of whom were of a darker complexion. I've seen her bark and act aggressively toward others of a darker hue as well, especially our next door neighbors, who are middle eastern. Angel barks and growls at them every single time she sees them. My neighbors made the comment that they thought she would be used to them by now, and they're right. They have just as a reliable schedule as I do, so Angel sees them regularly. I don't know what to do about it, as I've tried many different techniques both positive and corrective; I've also brought it to the attention of my trainer, but her techniques haven't worked. I'm running out of ideas, so much so that I'm seriously considering one of those vibrating e-collars (not the shock collars!), but I don't know if that would be appropriate or even helpful. I would appreciate any help anyone can offer. Thanks!
