I think this is accurate of what I just felt! I CAN feel his spine and last two ribs, but I do have to push a little bit. I guess I'll have to cut back on food a little bit...He has a bit of a silhouette when viewed from a above, and a bit of a tuck when viewed from the side, but not as much of either as he should have. I can feel his ribs when I pet him but not as much as I should. If your boy is also like that then he likely needs to loose a pound or two depending on what his ideal weight should be.
