Heat the oven to 375 degrees. Line a baking sheet with parchment paper and set aside.
Unroll the crescent dough sheet on a lightly floured surface and separate the triangles. Cut each dough triangle into three equal pieces, creating a total of 24 thin triangles.
Place one little smokie sausage on the wide base of a triangle. Roll the sausage toward the pointed end of the triangle, allowing the dough to overlap and wrap around the sausage. Place the rolled sausage on prepared baking sheet, point-side down.
Whisk together the egg, 1 teaspoon water, garlic powder, onion on powder in a small bowl until smooth. Brush the egg wash over the dough and sprinkle with the poppy seeds.
Place in the oven until the dough is puffed and golden brown, 12 to 15 minutes. Remove from oven and transfer to a cooling rack. Serve warm with your favorite dip or sauce!
