I found the pictures, read the post below first.

This was the day before he went into the hospital.
















This is my typical pathetic puppy. He loves to have his belly rubbed, even when he's really sick.





















This was taken yesterday when he got home from the hospital. The red bandage is from his IV. You can see how gaunt he is, poor puppy. He's really happy in this one though, he's surveying the house, happy to be home.
















This is this morning, you can see how naked his belly is, and his incision and his staples. He's so skinny and weak that he's always limp.
