My yorkie can't eat necks.   Chicken and turkey necks, absolutely not.  The bones will get stuck in the throat.  No big loss--not much meat on them, anyway.  Beef necks are safe for him to eat, but they just don't work.  It's like eating a lobster bare-handed.   Hearts all all kinds, though, are totally awesome.  But there are those big strips of fat you need to cut off.  Dogs don't handle fat too well.

Time out for a emoticon test drive.

(( EDIT: Both BBC and HTML work. Cool ))

Turkey necks are cartilage, muscle & skin only.  We'd buy them in 40-50 pound frozen blocks from a poultry wholesaler.  We'd get the tripe in similarly big frozen blocks.  We'd have to partially thaw them, separate them into meal-size portions & re-freeze them.  Real pain in the tail.  We also had a meat retailer who would prepare frozen patties of ground beef, veggies, & fruit - they were much more convenient, but the turkey necks were far better for the dog's teeth.  One turkey neck was a meal.

Glad we don't do that anymore. 

Anything good for the dog's teeth I'm all for.  I do raw beef soup bones.   My stinker absolutely loves those.  A little too much, in fact--he growls me off whenever I get too close...to the soup bone that I just gave him.       LOL

I had the vet do my dog's teeth while anesthetized once, and that was at the same time he got stitches from a bigger dog biting him anyway.   I just hate having him sedated. 

Yeah, sedation is worrisome. Not too many bones or they will cause problems by chipping or wearing the teeth. I feed them, but only once a month or less.
