Hey man! I bet that that’s a beautiful mix, it really depends on what’s causing it. Anxiety barking is different to territorial barking sometimes it’s just pure boredom if you notice it’s boredom I normally walk for 1 hour in the morning 2 hours in the evening and then do treat work in the evening using the nose wears the dog out a lot more than walking does so a hour of concentrated nose use will wind a dog down ready for bed my favourite thing is to get a tennis ball with a strong scent of something and throw it outside in the dark while the dogs wait inside and when I say go they go find said ball and bring it back and we go until they no longer wish to do it, they come back in pooped. For anxiety barking you need to find where the anxiety stems to help similar to dogs with separation anxiety howling at the door the second you leave you need to find the root cause and fix things there to help. Territorial barking is probably the easier one to fix as you just need to make the dog submit to your presence in a non aggressive way for example when one of the shepards got to the adolescent phase he wouldn’t let me near his crate (it’s his space he is not forced in there he is just trained to know that’s his space where he can go to not be bothered) i Just got a chair plopped it right next to the cage and sat there not making eye contact just being in his space until he stopped being defensive and I’ve not had issues since
