Hi Tommo
Is the bakers a puppy type ?
Did the breeder have the puppy on hills to start of with ? I would have tried to persevere with the hills as puppies often go off their food for a little while and also the very hot weather maybe affect the puppy as well.
I would say however if you are in the middle of changing the food,it is a puupy food,she is just eating that and leaving the other then just stick to the new food as at least you know she is eating so long as she is not having any adverse affects like an upset tummy!
