I was going to say maybe Henry didn't know what to do with it. We tend to think it's instinctive but maybe not!
When I gave mine a whole egg, they knocked it about for a bit, unsure what to do.
One of our previous dogs also cornered a pigeon but then didn't know what to do with it -fortunately!
Raw wings - Maddie gets to eat hers by herself. She's very ladylike and crunches away through all of it. Bramble is the gobbler. She bolts everything down. Wings did go down whole then came back up frequently, so now I hold them. I do actually put them horizontally across her mouth so she has to chew otherwise they'd still not be chewed much. (Not sure if this is the right approach though)
Do be aware of fingers though. OH ended up with trip to A&E after not paying attention!
