Frozen Marrow Bones

Today I stopped at a local butcher shop to get some marrow bones for Isaac. People kept telling me I should give him frozen marrow bones. Turns out the butcher shop gives them away for free, so yay, an affordable treat! Isaac is happily gnawing on one now and is even mostly staying on the towel I put down for him because I did not really want a raw frozen bone on my carpet. He says it is most delicious.
