Hi Schouiffy, So sorry that you are unable to go out even for groceries… internet shopping in the short term? And she does look very serene looking over Edinburgh... how pictures can lie!
My thoughts would be, yes the changes could have unsettled her and made it more difficult for her. However I am assuming that in the past there was no bad association with the crate or her being left and it sounds like she just doesn't want to be left alone / be shut in her crate rather than a specific issue associated with you leaving her/ being shut in the crate.
It may be of use to find a good veterinary behaviourist as whilst you work on these issues using DAP collar and an appropriate sedative could make life easier for you - the medication would not be a permanent 'fix' but just get her mind in a better place whilst you work on this.
Also if might be better if you tried a smaller crate? And I would be tempted to try with it completely covered - one she can't see a reaction from you - and dogs typically like small dark places.
Be it crate or car, I have worked on the theory that wherever I want my dog to settle I make it VERY comfy - just recently I had to transition from using crate in the car to back of car with guard as I got another dog - everyone laughed when they saw the 2 duvets folded in the back, but my little guy who had never slept in the car (because there were too much to see) now settles down to sleep, even with the additional distraction of another dog. I don't have my dogs up on the furniture (unless by invitation) so I would have the only soft bedding in the crate, and the crate would be sited in a good spot. I don't make a big thing out of going into the crate when I first got them, its the comfiest place they are allowed so they soon regard it as their bed.
When Tadgh was little I just bit my lip when I saw blankets/beds being chewed and shredded, but in fairness he never completely destroyed them and my attitude there were his bed so he was free to do what he wanted with them. I would suggest some cheapie fleece blankets which wouldn't be too hard to clear up, but she could make a nice nest in them.
Assuming Lycia is a good eater I would only feed her in the crate - eg pop her in the crate and give her the food do this for a few days so she knows the routine and then when she is doing this as normal, eg after a 10-14 days close the door. Don't make a big fuss about closing the door, just close it normally. If she kicks up a fuss - which I would expect her to do, open the door remove the food. It it is vital that you do not make eye contact with her, talk to her, just ignore her if she is kicking up fuss just remove the food quickly and put it out of sight. Once the food is out of the way, sit down as if the incident had never happened and if she comes up for a fuss, great give her some quiet attention. 30-60 mins later try again. If she does it again, remove it and then try again the following day.
As she knows that throwing these noisy and violent behaviours will get the crate open - and I don't blame you for her own safety as well as ensuring your neighbours don't get upset - you have to out-think her that by the crate door opening something that she likes will disappear too. I would expect her to starve herself for a couple of days, but if you keep going with this and giver her no reaction I would think that by day 3 she will have worked out that her antics are not getting her the desired result. If she does start to eat then as soon as she has finished open the door. But don't make a big fuss of her - its normal for dogs to eat in crates door open or door closed - and the end result is you want a dog that is happy and relaxed in or out of a crate. Just say what a clever girl she is and get on with whatever you were doing. She will then realise the 'power' the crate had is diminished. But it is important at this stage she is not left with the door shut and that these door shut times are frequent but very short 10 seconds - 2 minutes with her being sensible.
Again if she has a favourite toy or meaty bones, then try the same thing. Eg remove all her toys and she only get to play with her toys when she is her crate with the door shut - don't be surprised that she kicks up a fuss, merely quickly open the crate and remove the 'goody', again ignoring her completely.
If she loves going out for walks in time the 'game' can be extended so that she has to be in her crate before you will put the lead on. Again you'd start with the door open, but until she is her crate she doesn't get her lead on, when this is working well, then add the door closing as before.
Hope these might have given you some ideas to work with.
I find my most effective training takes place when I've done the thinking before I attempt it - eg what will I do if he does this... what will I do if he does that... my timing is then much better and I'm not caught trying to think how to handle something.
The other thing I would recommend is doing brain work with her - I've just started classes for the bronze KC with Tadgh - and I love the time after our class - even the following morning he is still mentally tired out!
