I would not make him his food anymore, as he's not eating enough to stay healthy.

Instead, I would go right to a local PetCo or PetSmart and buy Nature's Variety InstinctRaw Patties.
You will see a refrigerator near the food section with the word INSTINCT on top.

They're expensive, but they will 1) save you time and 2) give your dog a complete meal.
I am positive he will eat all of this.

I can't believe they couldn't remove the stones from his penis. Don't understand why they can't slice the urethra, get the stone, and sew shut.

Poor dog.
