Toad be or frog to be

I was watching Dillon from my patio while grilling out a few weeks ago and noticed that he was chomping down on something.  It looked like a piece of meat from the grill, but I knew that wasn't it because I had just fired the grill up.  As I moved closer, I was stunned to see two helpless frog (or toad) legs hanging out of his mouth.  I didn't know if eating frogs were safe for a dog, so I shooed him away as a piece of frog torso fell from his mouth.  After a phone call with the vet, they assured me that it shouldn't harm him.  I didn't have my camera handy, otherwise there would be photos posted.  Since there wasn't much left of the frog, I guess it is just as well.
