I never said you were mean!!!!!!!!!!
I love that I get to see what you look like - finally a face to go with the sense of humor.
You and your four-leggeds are so cute. It shows how much you adore them and they you. You are a great mom!
Yes, Jemma is submissive in her face, but its not like she is quivering on the ground. This is doable.
Voice is the biggest thing I hear as a potential issue. Your pitch is high and doesn't change much. Dogs are masters of tone and body language. Standing sideways to her can help but I think tone changes are worth trying.
We talk alot about tone. Have a 'directional tone' when you are asking for something. Sit, stay, sleep, etc. It needs to be slightly different from your everyday voice so they can discern it from your regular talking.
Want to really be a dog whisperer? Then WHISPER!!!! for the reward. Whispers have NO tone at all like you don't want to wake the kids in the next room. You can even whisper with a lot of energy and it is very rewarding to them. It will even draw them into your space.
If the dog doesn't comply to your request then you can use a firm (not loud) tone to let them know they didn't make a good choice. Be ready to whisper the second they do make a good choice.
In one of the last videos when you let the dogs out and they barked - you said something like 'don't bark', but your tone was so happy you might as well have said 'good bark!'. Try saying the word 'pizza' in 3 different tones. See how convincing you are. Test this on beau - have him help you with your tones. Oh, and in one of the videos you were giggling - yes it was cute - but it doens't help the dogs to take you seriously.
How vital are the treats? Their focus is very intense and that is great but it seems to be all about the treats. Try doing the same drills without the treats and things might even change with that. Jemma is so focused and ready to give all for the treat - she seems to get almost emotional about it. I would toss the treats and just reward her with your soft whispers, soft touch, and sometimes playful joy. Let her know when she does something well that you are so proud and pleased. Get her moving and on her feet sharing in the joy. It will help to keep training more fun and less pressured.
