Here is What to Expect
1
Size & shape: They retain the original heart shape, which is kind of oval or teardrop-shaped, and about 1–2 inches long.
2
Color: A dull grayish-brown or tan, due to the freeze-drying process (they look much lighter than raw chicken hearts).
3
Texture: Dry, lightweight, and slightly spongy or crumbly if broken apart.
They might look a little odd if you're not used to organ meats, but dogs absolutely love them.
