I have 2 rescued dogs (labrador mixes), the older one is the alpha in the relationship. They exhibit a lot of problem behaviors and definitely need some work, which I am willing to do. Recently the younger (non-alpha) dog ran off our property (she was off-leash) to a small dog that was being walked on a leash and proceeded to try to kill it. It looked like she was attacking prey like a rabbit or something. I tackled her and got her away, not before she inflicted a bite wound. My other dog was right behind her and would have happily joined in if I hadn't stopped it. This was the first time I have ever witnessed our usually very submissive dog attack viciously. Why would she do this? They are both aggressive while being walked on leashes toward strange dogs. I would like to get control over these dogs so I don't have this happen again. They also are not trained to come on recall, so I need to do that. Is it possible to trust this dog off leash even after a lot of recall training?
What would you recommend for my first step - ignoring them both for 48 hours, then starting basic commands? I am just beginning to read the training book. Thanks in advance.
