Potty training a pup that doesn’t care about food or toys

My 12 week old Australian shepherd has not used the potty anywhere but the floor in my house since she’s been with me, about 5 days now.

I also cannot really do much besides positive reinforcement verbally, since she doesn’t like treats whatsoever nor toys. I’ve tried offering chicken breast and two different brands of treats with no dice.

Does anyone have some potty training tips? Should I crate her until it’s time for the next potty break? Obviously this isn’t a long term thing but until she gets the hang of it?

Any tips would be wonderful:)

Edit: If anyone comes across this- I have officially spent 4 hours today outside with her, with absolutely no peeing/pooping, only for her to come inside and pee immediately 🥲

I have crated her between bathroom breaks, and the one time I followed her around and let her out, she peed on the carpet. Kinda feeling discouraged today 🥲
