Hi emmygirl-
If your dog is truly allergic to all the proteins that you’ve listed you will be hard pressed to find a food he can eat aside from a theraputic diet from the vet that has been hydrolyzed. If that was not offered to you as an option then it is likely that a hydrolyzed diet would impact his PLE negatively.
It sounds like at this point home preparing his meals using BalanceIt is going to be your best option. Especially if you are working with the BalanceIt team and your vet to create a diet that is specific to his illness.
My suggestion would be to get a crock pot and cook in bulk for him and freeze the meals. If you are a member of Costco or Sams you could buy meat veggies etc in bulk and it might be more cost effective that way. Most people that feed raw or home cooked meals set aside a day during the week or on the weekend as a “meal prep day”. It can be time consuming, but it allows you to prepare (most people do a months worth) food in advance for him and freeze it, so all you have to do is thaw it out twice a day. That would be my suggestion to you.
