I’m sorry to hear of your health issues and dog passing away recently. I myself struggled when our family dog passed away.
It would be best just to create a new post asking for South Korea breeders/pet stores in the title to get more responses. There were a couple people active on here last year that live in South Korea and had hedgies, I’m not sure if they’re still active but they might respond
I imagine it is similar to here in Japan and they are sold in pet stores or even hedgehog cafes. Try looking up exotic pet stores, that would be the best place or a reputable breeder but they don’t have licenses here so I’m not sure if they’d be better to be honest...
Although I’m not sure if a hedgehog is the best pet if you suffer with anxiety. My partner has anxiety and when it was bad he couldn’t hold our boy because if he was huffing and popping on his lap it made him feel worse and I’d have to take him off of him. Everyone is different though and has different coping mechanisms. Might be worth considering a more calmer animal, just from comments that my boyfriend has made. Of course he loves our boy and enjoys spending time with him but if he’s having a bad day and so is our hedgie it doesn’t work for him. I love snuggling with my boy but not all of them like to cuddle and sometimes he is hard work, it really can depend if you get a friendly/well socialized one or an aggressive/shy one. All I say is ask to hold it yourself when you go to buy one and if it won’t uncurl from a ball, I wouldn’t buy it. It will take a lot of work to get it to be social. If you hold it and it’s sniffing around then it will probably be tamer. This is just my opinion of course.
Hedgies can also have many health issues, which I’ve found quite stressful to do deal with (I’m currently dealing with an ongoing vomiting issue with my boy ><), especially living in a foreign country myself. So perhaps another thing to consider if this could make your anxiety worse. If you do decide to get a hedgie, I recommend reading through all the care guidelines here, they helped me massively to prepare and the community is great for helping with any questions etc.
Please don’t take any offence to my post, I’m just trying to give you some advice so you can decide if a hedgehog is the right pet, since you mentioned your health issues. I’d hate for you not to be happy or end up feeling worse if you weren’t aware of some of their behavior or health issues and have to surrender the hedgehog.
Whatever you decide, I hope you enjoy having a new pet soon! ♡
