Dog Noise Anxiety

Hi, I have a GSD male who has dreadful noise anxiety. Hard not to go into too much detail, as, with all anxieties, it is complex. It's a daily thing from sun up until after sundown. Any external noise (car doors banging, people passing by outside talking, etc) will set him off barking, that, in itself, is manageable, if very annoying. However, if there are ladders about (e.g. window cleaners or anyone doing work on their house - I live in a built up area), he goes absolutely bananas, and not only that, will keep behaving like that for 2-3 hours afterwards. Same if anyone comes to the door, or, God forbid, I have to have any strangers in to do work in the house; he'll go bananas, barking his head off while they're here. He's separated in a room, but poor boy just runs around barking and whining till they've been gone a while. Not good for any of our nerves, and I worry about him being stressed for such long periods of time. So, I suppose, noise anxiety and protective anxiety. My previous male GSD had a dreadful fear of trucks, particularly when they're backing up and beeping. I used aconite napellus for him with quite good effect. I've received this today after researching it's likely effectiveness for Teddy's issues, but I can't remember the dosage or frequency. I was also thinking that phosphorus may also help him, but naturally want to try the aconite first. Any advice re dosage and frequency?

Also, my female GSD has recently been diagnosed by the vet with early renal failure. Prior to that she had been experiencing nocturnal incontinence off and on (she's 8 and was neutered when she was less than a year old). She was doing quite well for a few months on the medication from the vet (Propalin), but a couple of months ago, even after adding Incurin to her med regime, she got worse and was noticeably drinking a helluva lot more water, with a subsequent increase in incontinence, naturally. Initial blood tests showed her electrolytes were off indicating possible renal failure, a subsequent more 'in depth' blood test was less conclusive but I'm being urged to continue treatment for renal failure and alter her diet as well. I don't notice any benefit from either medication or diet BUT I have recently noticed a pattern. I work night shifts, and it wasn't until I was off sick for a week, that I (belatedly) noticed she's much worse when I'm working. There really isn't much difference in the length of time overnight she has to go without water or get out for a pee whether I'm working or not, so that got me thinking. She's always had dreadful separation anxiety. I've created all my dogs as pups for their security, both physical and psychological, but managed to get them out of it by around a year old. However, I've never managed to get Mena out of her crate. If she's left uncrated at all, she just totally panics and runs riot, risking hurting herself to get out. When my last male died and she was alone for a few weeks (obviously only when I was out or working), she chewed through an airline approved crate. I tried her loose in the kitchen with a high gate, and she hurt herself trying to jump over it. She's better now with that since Teddy arrived over 18 months ago, and is crated again, but she is obviously still experiencing separation anxiety, even though it isn't as extreme as when she was briefly an only dog. When I was researching Teddy's symptoms, I came across pulsatilla, not only for urinary symptoms but also her apparent type of anxiety "Anxiety of solitude. Timid, craving attention but not returning affection, they dislike being left alone ... the dog with the changeable mood which wraps itself round the owner's legs for reassurance " ... That's Mena! Any advice re that as a remedy for Mena?

Thank you so much for your time and consideration:)
