I understand; lockdown has made addressing things like this increasingly difficult.
Bullies are clever dogs who are used to being kept active and using their mind. I would ensure she is being brought on a variety of walks and is able to sniff and explore when out and about. Simply getting from A to B is not the aim, it is more about wearing her out mentally and providing her with a nice distraction. When out, we should play fetch, 'find the treat', practice her recall etc.
With regards ***** ***** the barking, all family members must be doing the same thing consistently. For example, if we choose to ignore (which is what I recommend), everyone ignores her until barking stops. This means no talking to her, shouting 'stop', saying 'no barking' etc. It even means no looking at her. We act as if she doesn't exist. Once she stops and settles, she gets praise and a treat.
We should also work on teaching her a stop barking command such as 'Done'. We can work on this at times when she is not nuisance barking but eventually would hope that it works to control the nuisance barking too.
Barking is often a sign of frustration and boredom so ensure she has lots to keep her occupied when home such as food puzzles, interactive toys etc.
Non prescription calming supplements such as Yucalm and Zylkene are worth trying but you may need to move up to prescribed Fluoxetine if they do not help.
With regards ***** ***** vet, which would be great, you would need to call you local clinic. Many are doing over the phone consults and will then see a dog in person if they deem necessary, Given that baby is due soon, they may well be happy to see Luna.
Hopefully we can start getting this sorted as a barking dog is not something you want when trying to settle a newborn!
