Mine is more like a cat - when I take her outside, she has to sniff every crack and craney - and she even gets up on her hind legs, and checks out the flowers in the flower pot.
Her sister who is here a lot sleeps on her back all the time.
They both love to chase lizards, sniff tarantulas, bark at javelinas and deer. Mine tried to attack a javelina once, and I grabbed her just a foot from the pig. It was terrifying! They are sweet, interesting little creatures, yorkies.
