I adopted a nine month old puppy in May. And since I've had her it's been endless stress. Let's forget her puppy behaviors - those I can deal with. But her reactivity, I can not. She barks, jumps, and lunges at anything unfamiliar. For some reason old ladies are a trigger and she's bloodied my grandmothers arm twice from jumping relentlessly and swatting her. Once while on a very short leash but still within striking distance. I can't trust her at all. I'm afraid to have people over because of the way she acts. I can't take her in public. We've been working with a certified trainer but her reactivity isn't getting any better and I find new triggers daily (it was a bag of garbage last wk). I don't know what else to do and I'm thinking of giving her back. I'm riddled with guilt because I spent so much time. I combed through PetFinder ads for months, researched, drove three hours to meet her, drove back a month later to pick her up. I've spent so much money on her - but that doesn't matter to me. What matters is the time I've invested in her. She has literally been my project for the past six weeks. I work with her several times daily and while her overall behavior may be better - her reactivity is not. And I'm afraid the reactivity will manifest into aggression once she realizes what she's capable of. It's just so sad. I was so looking forward to getting a second dog but it has been nothing but an endless source of stress.
