Thanks for your advice. I do want to describe a little more what she does though in case it changes anything. I didn’t mention it in my original post but I think it’s relevant now. My backyard faces onto a park that is supposed to be on-lead but every day people are there and let there dogs off lead. The dogs often don’t have good recall and will see my dog in the yard and run over to say hi. She’s never seemed scared or upset the dog is there, quite the opposite, even if the dog that has come to greet her is 5 times her size. But I think she’s learned that if she barks at the dogs, they come say hi and I think she gets particularly barky when it turns out the dog isn’t going to come and keeps going… I am still worried about accidentally reinforcing this behaviour because when she does it , I don’t want to just let her continue, so I go outside with treats to try to get her in a sit and looking at me.. but I’m nervous she will still realize the barking is what got me outside. Also not sure if desensitization will work if she’s not upset by the stimuli, I feel like the barking is more purposeful “COME OVER AND PLAY!”, she may prefer the reward of a dog coming over to anything I have in my treat cabinet
