Disappointed in Waggies Dog Food

I am very disappointed.

I bought my dog waggies puppy food. She ate a little bit and started vomiting.

Next morning I gave her some other puppy food and she ate it.

Later the same day I tried waggies again, she ate a few pellets and vomitted again.

When I give her other dog food nothing is wrong.

When I try giving her waggies she does not even want to eat.
