So, I'm considering this as a new RMB for Frodo, but I can only get it in 20# cases, so I'm looking for some input from those who have fed them. First off, are they hackable with a butchers knife/meat cleaver? And would you consider them a tooth breaking hazard for a medium sized dog (Frodo doesn't get weight bearing bones or processed hooves or antlers etc. because he will break teeth on them)? I'm trying to find a turkey neck replacement that is either pork or beef due to his allergies. Thanks!
