This is working very well with our 2 yr old rescue shepherd mix. When we brought her home she was vary aggressive barking at window etc. so as someone suggested, just work on one issue at a time. It took 3 x and she has stopped. She was horrible with the mailman, but now she just looks at me and whines a little.Now we just fixed not lunging after anything when on a walk, I say Corky No, and if she continues then I use the device. Again, maybe 2-3 times using it, now when I say Corky No she drops down to a lay down position, and mostly doesn’t start to lunge at all.Next up is the little nibbling she tries when we have a guest and they stand up or walk by......this is taking longer because of infrequent opportunities.Love this device, simple and effective if you follow everyones suggestions.
