I homecooked for awhile. This recipe would not be fed here either.

Avoid garlic whenever possible.
Balance the supplements - you are probably missing calcium too.
Too many vegetables for a dog losing weight. Not calorically dense enough.
May be lacking fat.
Your pups are being underfed.
Whitefish is okay, but not great for weight gain.

A board certified veterinary nutritionist is needed. Anybody can call themselves a nutritionist, but that means nothing. Very few vets know how to properly balance a diet. If this isn't working out, probably time to try dog food again..
