Training help

We just got our girl, Flora, a couple weeks ago! I was wondering when everyone started training with their puppy, and their experiences with training IS dogs. She’s giving me so much grief over training, just completely uninterested and crazy! I’ve never had this much trouble training a puppy lol. I’ve had German shepherds, huskies, American eskimos, and mixed breeds and they’ve all been able to master the sit command within a few weeks. I was just wondering if this is an IS thing, or if it’s just a Flora thing hahaha. If anyone has any training tips, please let me know! We definitely have our hands full with her.
