I've seen several dogs that bark aggressively when they are separated by a fence, but get a long fine when there is no fence. I don't really know how to predict their behavior with no fence. By the same token, lots of dogs are more reactive when they are on a leash, probably because they know they can't run away or fight back if they need too.
Thank you very much for the reply. Do you think or suggest weekly outings like this, with taking things slower will benefit her? To me, she met my dog I already had just fine. She reacted the same with him as she did with my friends dogs, only difference was there was no fence between them. She was able to just meet him. But I didn't want to have her meet these dogs like that because I don't know her dogs. I knew my dog, and how he would react, so I was more confident in introducing them. My friend was even surprised with how her dogs reacted to Abby. So I'm glad there was a fence there. I will slow things down, and if you think continuing these meet sessions will benefit her in the long run I'll continue to do so. At a much slower pace. Because I also think her dogs will continue to react that way if she continues to behave this way.
I completely know what you mean. Abby and my dog I had before her met at a lake, and their meeting went fine. No fence between them. She reacted the same way she did toward my friends dogs, jumping, lunging, and barking non stop, but things went fine. Once she sniffed him she stopped and we walked around a bit and they've been buddies since. But I don't want her to act this way because not all dogs will behave the way mine did toward this behavior. As I saw with my friends dogs. I also feel Abby is very leash reactive. But, I've never had her off leash to see how she'd behave.
I would work on her more frequently than once a week, with more than just these dogs. But, remember, at a distance where she doesn't react. Look at the advice on this thread and follow the same protocols: https://thelabradorforum.com/threads/started-jumping-and-growling-at-bypassers.21942 Sessions shouldn't be more than a few minutes each, but practice with every single dog you come across.
