RAW chicken wings are absolutely fine - many of us use them as part of our dogs BARF diet. To a newcomer tho, you might find you have to cut it into sections or smash it with a rolling pin first!
Eggs, again I feed them raw - 1 - about 2-3 times a week, with her breakfast. again as part of her BARF diet.
Never feed cooked bones - ever.
Never feed cooked and raw together!
Theres loads of info on here about BARF, if you really want to take it seriously, otherwise a wing a day for breakfast perhaps, will help keep your doglets teeth clean and fresh
