It's just all very weird. The thing is, there's things that work short term but ruin your dogs confidence and bond which cause bigger issues in the long term, punishing the dog falls in this box. I mean, you can train your dog by kicking it every time it does something wrong if you like, it might work, but it ruins your dog. A lot of these fake trainers fall into these things and cause real harm.
That's really country specific, in the UK we only have one pine and it's not that common. We have a huge issue currently because after the wars they replanted a lot of land with pine as it was fast growing and we needed wood, but now they've outcompeted the native trees so there's a big program to get rid of the pine and plant native trees, but it needs to be done really slowly or the whole forest is messed up.
There's a bit of odd advice there. Not letting your dog cuddle with you and barking at them is very weird. Check your trainers qualifications. Leash corrections is a red flag too as is dominance based nonsense.
Exercise doesn't have to be walking, how mobile can you be? Can you hide food around the house? Or throw a frisbee?
It might be tricky to teach but if you're stuck in one spot you can get a couple of balls and play fetch, you hold the second ball, refuse to throw it until he brings the first one within reaching distance, smart dogs get that quite quickly. It also helps their brain cause they have to work out what you want them to do.
Talking of the brain, sometimes thinking is as good as doing, so you can set up puzzles, set up a frozen kong, all sorts.
I'm a fosterer with quite a bit of dog training education. I second the advice that you need a good qualified behaviourist, this means degree level study or above.
However, for the meantime, nobody should be taking anything from him by force. This will worsen the behaviour. The things he's taking don't sound like they pose danger to him so take all the urgency out of the response. It's anxiety driven so you want to make everything really chill.
Firstly, clear everything away, as much as possible get things in drawers or too high to reach. The less he can get that he shouldn't the better.
Work on swapping with a low value item like a toy he doesn't play with much, so say an old ball, give him the ball, get a treat and offer the treat while holding your hand for the ball. What should happen is he drops the ball, give him the treat, then hand the ball back. He's learned that nothing bad happens here. He gets the treat AND the ball. Do this 5 times in a row, then leave the ball with him. He's learned here that it's all very chill and you've reduced his anxiety.
As he gets better at this, increase the challenge slowly, maybe a toy he likes a bit better, then better again. At this point you can also start swapping items, so you take a teddy, give him a treat, then give him a ball. If this makes him anxious then slow down, you want it to be really chill for him.
Eventually he'll start giving you stuff just to see what he can get. It's a fun game.
Another exercise you can try if he does get something you don't want him to have is to throw treats away. If he has something you can throw a treat in one place, then another, then another, while he's having a great time, quietly remove whatever he had, he'll probably have forgotten he had it, but make sure it's quickly hidden to help, give him loads of fuss when it's gone for extra memory wiping!
Also make sure he is getting enough exercise and attention, and he's not in pain, these kinds of problems usually start if a dog is feeling crappy for whatever reason.
I taught teenagers for a long while, the things about teenagers that are annoying are also so very relateable. They're full of hormones, incapable of handling their emotions, and way too busy coping with all of that to be in school.
A lot of adults seem to have amnesia about that time but spending time with whole classes of them makes your own experiences of it flood back.
Like when a guy you liked didn't say hi to you in the morning and you had a whole existential crisis that nobody would ever love you, cried in the toilet at lunch time, then decided you were a strong independent woman, got over the whole thing, by the end of the day you were like "screw him, I deserve so much better!" then you saw him leaving school and he was like "Sorry I didn't say hi earlier, I had my headphones in" and it wasn't actually a thing at all? That's basically being a teenager all the time.
I mean, boxes in general are my organising style. I keep a lot of aquariums so I bought 8 shoebox sized boxes, one for substrate, one for decor, one for water testing, etc.
In my bathroom I used to have a lot of stuff so I bought a few wicker baskets, hair stuff, skin care, and make up, then a tall cupboard with fabric boxes for cleaning products, toothcare, hair dyes, bath bombs, you know. I have boxes everywhere.
If you know how to take care of fish, there's some fish that are more personable. I had a Butterkoferi Tilapia at work who was fun, he would play with a ping pong ball, we had a constant fight on how we decorated his tank, I like gravel to be nicely spread out, he liked it all in one corner.
There's things like flowerhorns who like being stroked, or puffers who recognise their owners.
That is a very long email filled with a lot of waffle which is based on things you seem to be worried about due to not understanding the situation. I'm not helping you with everything but read what you're typing, you've put a post about needing explicit consent to use DNA and then made up a story that people can be tricked. Not how it works.
The screenshot you've found of Gedmatch isn't anything to do with police at all.
Finally, you've claimed I haven't answered the court case suggestion, which I did a message or two ago. If they have a case strong enough to get your DNA then they can get it from you. No need to go faffing about with websites.
To use genetic genealogy you need access to a database of users, each of those peoples data is protected and in order to use them each time you would need to make a valid case for each persons DNA. That means hundreds of thousands individual cases and you wouldn't get permission as theres no cause.
