I don't think there are any just meat dry foods. The grain free foods still have veggies. There are some great foods that have the first 4 or 5 ingredients as a meat.
You could try some pre made raw foods. There are some brands and formula's that are just ground meat.
Some dry foods are more expensive than raw. That should be factored into what you choose. Big pet stores (Petland, Petsmart etc) don't have a great selection on good foods and if they do, they are expensive. Small, independent stores have a better selection and prices.
