On Saturday, I finally got a new puppy!

The breeder didn't give us any of her food. And I failed to ask what she had been eating. I normally use Science Diet for puppies (my vet recommended that) so I just gave her some of that Saturday night and Sunday.
Today, she hasn't eaten anything and only has been drinking a little. I'm guessing it's a diet change...but I would really like to be reassured.
Thanks to everyone in advance!
