We went to the vet yesterday afternoon after I found blood in his stool. I panicked because I know it's not a good sign. He's on medication for his diarreah now and he's eating hamburger and rice. He seems fine though. Still wants to play! It's hard because he's so small. I've never had such a small dog so I tend to treat him like a baby and panic at little things. Good news though, he's gained 2 pounds!
