I just need to get this off my chest because the last 3 years of my life have been spent trying to figure out how to help with my dog's behavior.

She's had issues with dog leash reactivity since I rescued her at 1 year old which progressively got worse during her teen years. She can't pass other dogs without lunging towards them and desperately wanting to greet any and all other dogs. If she's walking near a more passive dog, she makes very loud (and frankly terrifying) snarling sounds that sound very aggressive while rearing up on her back legs. She's a nice dog and lives with two other smaller dogs with no issues. It's when she's leashed is where the issues start. She's a frustrated greeter and often intimidates or angers other dogs because she's so excited to say hi that it freaks other dog out. 

It makes walks and hikes stressful and I end up creating a ton of distance between us and other dogs and shove cheese in her mouth until her trigger is out of sight. I've seen some improvement with this but it seems she regresses back to her usual behavior even faster than I can condition her. I took her on an evening walk today and she was staring daggers at an aussie that was around 20 feet way. She wasn't looking where she was going and almost ran into a bench she was so focused on the other dog. I just wish she could chill out. 

The only thing that's helped is a head halter (sidekick) but she hates it and rubs her face on any grass she encounters trying to get it off. I don't think it's a great solution for hikes either. 

I'm going to keep trying high value treats and conditioning, but the progress is so incredibly slow... i'm feeling very dejected 😔 If anyone has any advice that they'd like to share please let me know. 

My girl is leash reactive, whining, barking, lunging, and intense staring at other dogs
