It's really called a martingale collar, but you use it as a backup with something like the gentle leader. Here is an example of a martingale collar:

I use that with a variation of the gentle leader myself, but it is a looser fit:

I also highly recommend you try to get your jindo used to it, by putting it on him inside the house and treating him while he has it on. Eventually the dog gets used to it. Ours will some time try and get off by rubbing on the grass, but then we just tell him to let's go and walk somewhere else.
I find that walk'n train to not sit as tight and bothers him less. There might be a deluxe version that has extra padding for extra comfort too.
Good luck, and don't hesitate to ask if you have more questions.
By the way, yeah Jindo's get overly excited outside and is easily distracted and love to stiff so the bunny hopping around is quite normal for them.
We used this from a very early age.

The trick is to show them and ring the bell EVERY time you take them out.
Try to get them to ring it before you open the door, even if they don't ring it, you ring it and then open the door.
It’s water resistant, very secure so doesn’t slide around and heavy duty yet super easy to clean which is great for fall/winter.
There are openings for the seat belt harness clip as well. The options others have suggested look good. I use a non-chewable one because my dog very calmly and quietly chewed through his nylon one on a road trip so he could range free in the back seat 😂 my dog is 35 lbs and the 31 or 36 Inch does the trick. https://www.chewy.com/leashboss-heavy-duty-no-chew-dog-car/dp/179196
Also, Euna is beautiful!
I have a hammock looking seat cover, and got the following harness with metal buckles. It comes with a set belt tether that is supposedly crash tested. Although the results are somewhat dubious, it's a step up from most others that aren't even tested.
I highly suggest a tether, because you don't want rough stops to throw the dog forward and etc. My dog refuses to go down in the car, as I suspect he gets car sik.
The coat gets dull and choppy over time. Not great.
The furminator is essentially a blade with a handle. It's supposed to take out the undercoat only, but the way it ended up being designed, it cuts the top guard hair layer as well.
You need a nice, handy slicker and this.
Here's a comparison image created by a well known Jindo breeder. First is a furminator, undercoat rake, a slicker, and a rubber currycomb.
> I don't like the Furminator myself, it cuts the guard hairs which can damage the coat.
What happens when you damage the coat?
> I recommend a slicker brush and an undercoat rake
Something like this?

Also, what is a "slicker" brush?
Edit: I see now what a slicker brush is.
I've heard great things about the Furminator but I use this $15 one from amazon and it works just fine!
Nothing about this is really Jindo-specific...
Toys are hard, but pretty much every dog seems to like treat balls.
General guidelines around crate-training should help, just read a few guides like this and average out the ideas.
Hand-feeding food should help with training, positive reinforcement etc. The trick of having your hand go slight above / behind their head helped us with "sit" a lot. You can even only give them food via training, if you like.
Our Jindo mix loves his Tumbo Tugger (Amazon link). He loves the toy squeaks when shaken and the bungee makes it really fun to pull, release and chase. :)
It has different tones/sounds/music and you can adjust the volume too. The transmitter is plugged in nearby so you can keep the chime in your space with the sensor at the door.
Yes, he's a KK9R alumni!!! It took us a while to figure out what he did and didn't like for his food. I think also it's partially due to their suspicious nature. It didn't seem like he initially trusted what we were giving him to eat, so he was always reluctant to eat. We tried adding some treats in his food to entice him, and sometimes that worked, but most of the time he'd pick around the food to only get the treat, haha.
This is the brand of goats milk we've been giving him, it tastes so good!
We've also tried Stella and Chewy's dehydrated dinner patties with Honest Kitchen — mostly because we needed dry food for camping — but really the goat's milk does wonders!
