[little pea]

I am new to this website, to all of these discussions, but would love to get some advice as I am searching for a dog food. My Newf came back with allergies to beef, chicken, lamb, cow’s milk, eggs, potatos, sweet potatos, rice, soy, yeast was very high, carrots, shell fish mix and fish excluding salmon. Can anyone suggest an excellent food? Ziwi peak is a bit expensive for such a large girl, and contains green lip mussels. Has anyone heard of Great Life or tried it?
