@tribmartyr Got it, thank you for clarifying. It could be several factors. Seems like you’ve done a lot of work to mend the original fear reactivity. Issues between dogs in the same home can be complicated and I wish I had more guidance to provide.
I know it can be stressful and exhausting to have fights and spats at home.
Inner home dog issues can have 100s of remedies depending on the causes. From books, videos, trainers, behaviorist, vets, etc. if you want to keep all of the dogs and it’s safe and possible to provide a balanced life, just know you have the support of this sub for sure. It’s changed my entire perspective to know there are plenty of other people that understand what having a reactive dog can be like.
The blanket advice I’ve been given that has worked thus far is managing the environment to limit triggers, using crates and muzzles to keep everyone safe when necessary, taking things slow and positively reinforcing boundaries and expectations for all the pups in the home.
I also have a female rescue that was fear reactive outside the home to strangers and other dogs on leash. But we’ve made progress outside the home.
The remaining hardship has been with my other dogs in the home. It’s been an ongoing struggle over the past 1.5 years and it isn’t easy. But every effort you make can make a difference and getting guidance from others is a great start.
I hope someone has a more thorough response for you. I’d recommend a behaviorist or looking into environment management to limit the negative interactions between the dogs for now. Hopefully you find some relief soon!
