We had a long haired chihuahua when I was growing up. His name was Joe and he was a beautiful fawn color. Sweet, and smart, dog. One night, though, he started shaking violently. We thought he was having some sort of seizure. Since he was holding his mouth open at an odd angle I thought maybe something was wrong with his mouth. I stuck my finger in his mouth to feel around and discovered he had a lima bean stuck in the upper part of his mouth right behind his teeth.
