 Well, I don't know that it's the spleen. I mean, that's kind of where the spleen is. So if you're going to feel the spleen, that's where you'll feel it. If it's under the skin but outside the dog's body wall, it's probably a lipoma. If you have an older dog and you can feel a lump on the spleen, first of all, you're a better veterinarian than I am. I can feel a big spleen sometimes.
