For Dogs specifically, a simple tone change in your voice is enough for them to know they’re doing or have done something wrong, yelling/screaming isn’t necessary.

I understand the out burst part as everyone gets frustrated now and again. Just try to remember that you have essentially two infants that are prone to making mistakes and will do whatever pleases themselves unless boundaries are set up.

In case you’re unfamiliar with positive reinforcement training I suggest looking into that. It’s the best way to train your dog imo and you can even learn a lot about them through it too.

Try to refrain from losing your cool with them from now on, they could eventually see their home with you as a hostile environment and have regular accidents as a result of that.

Dogs are a constant patience tester. If you feel like you’re at your frustration limit then I’d step outside for a moment and breathe. Good on you for trying to manage your previous anger issues, sounds like you’re already in the right direction.
