We have a female lab who was a rescue. She'd been abandoned to a garage during the time she should have been socialized and burned with cigarettes and lighters. With some hard work, we did rehabilitate her pretty well but now (about 3 years later) we have a lot of dominance issues as well as anxiety creeping up and I'm at a loss.
When we leave the house, she is kenneled- this doesn't happen often or for long periods. Still, she barks endlessly. Food/treats/toys do not help.
She's becoming food aggressive. She tends to be hard to keep weight on and is always hungry. The vet hasn't found a reason and nothing we do seems to help. She simply is a very tightly wound high metabolism dog. She had been growling only, but has started making half-meaningful snap at the other animals. I don't let the kids near her when she eats- obviously.
This morning, she snapped at my small dog. He had a toy and she thought she needed it. She snarled and snapped- hurting him enough that he whimpered for a couple minutes. (He's a chihuahua, so it really wouldn't take much to hurt him. :/)
She has been a great dog, but the behavior changes of the past few months really worry me. I love this dog, but won't risk the safety of the kids. She's been the quintessential couch-dog, and has always been great with the kids. She has never offered to behave in a dominant manner towards any of them, but I fear that if this progresses further I won't be able to say that. I can't allow that to happen as she would not be allowed in our home anymore at that point, and I don't expect she would be a good rehoming candidate, which doesn't leave a happy outcome for her.
Please spam me with suggestions if you have any. I trained dogs and ran obedience classes years ago but I feel like I've tried every trick in my book.
