The answer is no. Chihuahuas don’t have sensitive stomachs. They’re more likely to eat dirt than any other dog breed. The answer, of course, lies in their diet. Chihuahuas are often fed table scraps, and this is a recipe for a stomach full of foreign objects. When given table scraps, dogs can and will eat everything in sight. When given a healthy diet, chihuahuas are perfectly happy to eat their normal kibble with the occasional table scrap thrown in for fun.
