Swiss Hound puppy dont want to go out

We have a swiss hound puppy since a week, lately every time that we have to take it out, to make her do her business, she doesnt want to go out, at the beginning when we open the door she follow us, but after sniffing a little the garden, when we are near the gate, she start to pull the leash to return home, i tried first to stand still and ignore her howl and bark, waiting that she came for me, and giving her a little snack everytime she follow me, but now she doesnt care about the prize and when i stand still she pull the leash stronger and start to go crazy, lately i ignored her until she follows but i think its not the better solution beacuse i read that hound are good with positive reinforcement and they are really stubborn. I dont know what to do help pls😭
