Dumping it as in throwing it in the trash, sure, but there's literally NO reason whatsoever for dumping to cause any sort of problems to the original, how did you even get such an idea? Dumping is literally just copying something, even if you had the priviledges to write onto cartridges, dumping still wouldn't involve that, so it's always exactly as safe as copying any other file from one directory to another.
 
The only way dumping your cartridge would ruin it is if you dumped it in some water...or garbage...or acid...or...

Meh, water doesn't really ruin electronics, especially cartridges, just dry it and it works fine:P
 
Why on earth would it ruin it lol.

You laugh but I one ruined a rented copy of Secret of Evermore by dumping it on my Smart Bros copier. Dunno why, but it somehow messed up the sram. I ripped dozens if not hundreds of SNES and Genesis games on both this and my MGH before that, and while most worked perfectly fine as roms, a few wouldn't save properly as a rom or some other minor error, this was the only one that did this on the cart itself afterward. A year later, I tried to rent it again to try redumping it and they didn't have it anymore, saying someone had returned it saying it didn't work, whoops...
 
I didn't know if it could write to the cartridge
According to the GBAtemp wiki "Card2" 3DS games exists that have only one (flash?)chip for the game and the save which means in theory the game could be overwritten. (Or does the cartridge prevent writing outside the dedicated save area??)

Dumping the cartridges is - in my opinion - a good idea because nobody knows how durable/long-lived such 3DS games are ("data retention") opposed to "real" ROM chips (used in carts for older consoles and - as far as I know - Switch games again) which are already proven to last LOOONG, even under really bad storage conditions; in this case even the save on (EEPROM or flash?) survived.

Anyway: GodMode9 will never even attempt to overwrite the data when reading a cartridge. Why should it even try?

Obviously Nintendo made it so as only the dedicated save area can be written to. Otherwise you could have just wiped all data off the cart then copied a completely different game to it.

I think for me it raised confusion as the term “dump” sounds like you transfer the file from the cartridge to the sd card, I’m pretty new to this so as a non-tech person this makes sense

From the choice of words you used. no. You are Copying the ROM from the cart to the sd. Not transfering it sinces its a 'read only memory' item.
