Puppy Hiccups?

Daisy hiccups A LOT. She had done so since I got her a week ago, tomorrow. I'd say she has the hiccups at least 8 times a day, lasting for 30 sec. to 2 min. She was at the vet today, I told him, he told me not to worry, she would grow out of it, and if she doesn't, try a food switch (she eats 3 cups of Innova LB puppy, currently.) I'm not too worried, as she acts fine, and checked out healthy, but I wanted to see if anyone else has experienced this? Any idea if it would constitute a food change?
Thanks!
