Fantastic work man. When I get a second I'll watch through this again and then get a demo video of some tips and suggestions you can use to build on this

Short, structured play sessions or engagement sessions indoors a few times a day will always beat unstructured, mindless exercise outside. Happy training!

This is a deeper issue, and one that has to be addressed at the root if you want to have real success. Here's the general problem solving process I teach: 1. Identify the problem or goal (you should clearly be able to articulate it) 2. What skills/behaviors does the dog need to reach the goal? 3. Do they currently possess the necessary skills or do they need taught? 4. If needed, teach the skills. 5. Use those skills to teach the dog the desired behavior to reach your goal outcome. In your case the dogs do not possess the ability to be separated. So ask yourself what you need to do to first teach them to be content away from each other. Here's how I would work that problem personally: First you always need that communication system in place. In your case you'll have to problem solve this by either putting one dog outside or somehow completely removing them far enough away so the other dog can focus. Following my engagement building protocol will help a ton, especially if you lower their food intake for a week or two. They'll get hungry, thats the point. You have to out compete their desire to be with each other. If they are hungry, food will take priority at a certain point. But what will really fix this problem is having a solid way to say no. An e collar (properly introduced to the dog) is by far going to be there most clear and efficient way. Stay tuned I'll make an e collar conditioning video for you guys. This will give you the ability to crate the dogs and interrupt any protest barking in a way that the dogs will understand. So again, you are missing the ability currently to teach the dogs how to be content by themselves. Focus on building the skills needed to teach that lesson first, then use those skills to actually teach the lesson. Let me know if this makes sense, im happy to elaborate further!

@Lydia McFadden a good starting place that would give you an effective alternative to the e collar would be my recall course. You can find that in the classroom area here as well.

@Tyler Ervin if his engagement is solid inside try moving outside, just avoid walks and other dogs for a period of time as much as you can. You'll have to generalize thatreward system so he's expecting to have fun in different environments

@Aj Ryan it's not just you, most people are missing the last piece of the puzzle as far as how to actually desensitize a dog to a trigger. Its a nuanced topic, one that will be better addressed in a dedicated post, article or video that I'm planning on getting made for you guys. But the general idea is this: you need to have enough tools and skills in place so you can gradually expose the dog to the trigger, while also controlling and influencing the dog's state of mind. Progress happens when you progressively increase the distance to the trigger, difficulty, intensity of the scenario etc. Basically you need to be able to safely expose your dog to the trigger so incredibly often so that what was once overwhelming and stressful becomes....boring. More will follow stay tuned into the group. This is a complex topic with lots of bad Info out there as far as approaches.
