Child's Cup with dogs and possible tomb

I think this is a childs cup and fork of some sort. I believe the makers marks to be McChesney for the cup and Dominick & Haff for the fork. My question is what kind of child’s cup is this?? The engraved dogs are beautiful and it looks like they are guarding the entrance to a tomb of some sort. Interesting at the least - Any light shed on this unique piece would be greatly appreciated. I will post a few more pictures in the next post - Thanks
