Ideas to entertain dog that doesnt play with toys?

I have a English mastiff/ dogo argentina mix and she's the sweetest dog ever but I have the hardest time keeping her entertained and happy. She doesnt play with toys, no tug of war or chasing sticks, the only toys she seems to like are chew toys which are very expensive and last very little time with her giant mouth lmao, and puzzles, but once she's solved them its not as entertaining. Her other favorite thing to do is run but its extremely cold where I live so its not always viable to take her for runs Any enrichment ideas with searching, sniffing, puzzles, or chews that last and would be big enough for her?
