Bil Jac has both the dry and frozen. You are correct about the dry but the frozen was always keep in my freezer if I needed in an emergency. The University of Pa. Veterinary School always ordered for dogs after surgery that were not doing well and it pulled many through a difficult time.
Ingredients could have changed through the years since I haven't had a dog for some time but in the past it had been excellent with maybe a little too much sugar to ever use for a daily diet.
I'll have to go check and see what they say about it now.
