I saw on a youtube video one persons husky really like tangerine essential oil, basically makes their husky act like a cat on catnip. So I got some, but mine seems to be completely indifferent about tangerine oil.

Periodically on walks she'll find some smell in the grass she likes, and start digging in the spot a little, smelling a lot, then like roll over on her back and kind of act like a cat on catnip for a moment.

I don't know what smell she finds that makes he do that, but makes me think their must be something that'd induce that response in her? What are all the smells that husky's potentially really really like?

Rolling usually means something dead was there. Unfixed dogs will also pay heavy attention to the urine of other unfixed dogs. As for enrichment smells for mental stimulation a blanket that a cat has laid on is pretty high up on the list for my dogs.

Mine like dead things. I gave them a deer mouse yesterday ot was really funny. They like to roll in blood and deer poop also. But anything elk makes mine go crazy l.

Green, sticky, excessively stinkypossum poop is my big guys favorites scent to roll in...
