Oh, I realize I need to clarify. Ellie is only reactive to those stupid dogs who are charging their fences and snarling and barking at her while she is on a leash. She likes looking at other dogs who are also on leashes on our walks and sometimes she barely gives them a second glance. In another thread I mentioned there was a wee little Doxie that was running towards her barking it's fool head off and Ellie only looked at it with mild curiosity. She will also react if another dog on a leash barks aggressively at her first. This has happened at the dog park before. That gets her dander up. I can get her to sit perfectly well-behaved in those instances and tell her to watch me and she would MUCH rather get a treat than bark at another dog. In fact, she would rather eat than do anything else!
I am hestitant about obedience classes only because our first one was such a negative experience. In our first one, Ellie was 6 and a half months old and already knew how to do all the stuff we worked on. There were several VERY aggresive dogs in that class and that is where Ellie learned to bark (I am totally serious) and she also got tired of getting growled and snapped at and started to get defensive back. The last day of class Ellie got bit and so did I by the same dog. It was a sneak attack. The owner never said one word to us! She SAW the dog bite us! I was furious!
She would be eligible to go to an advanced obedience class now and I think if the other dogs in the class were well-behaved, she would be too. I certainly could talk to the instructor and explain what has transpired with Ellie and ask about the other dogs in the class and decide. If the instructor says other dogs in the class are aggressive, then I will pass. Knowing Ellie, it would make her worse and I don't want to go backwards.
I have thought very often about getting equipment for the backyard for her. I honestly think she would love agility. I just wish someone would have classes to teach how to work with your dog.
