As far as I know - and I bow to Bid on all things diet-related! - you can give a dog raw meat, raw eggs and raw bones pretty much as you like, so yes, you can absolutely throw them a chicken wing or a marrow bone now and then if you want to see how they get on with it.
The only thing that seems to be a no-no is feeding kibble and raw in the same meal. My solution to that is to feed raw in the morning and kibble (if I'm going to) in the evening so his stomach has a long time to digest it.
I love feeding raw, Woody seems to be thriving physically (touch wood), and he definitely enjoys his food. I can't remember the last time he turned up his nose at anything. But it is definitely more of a faff than going to Pets at Home and just buying a bag of kibble and pouring it into a bowl every night.
Health - arguably better for the dog and anecdotally a lot of people on here have had significant improvements in their dog's health problems and overall condition from making the switch.
Enjoyment for the dog - Woody was very indifferent to kibble, even the good ones, whereas he so far has never shown anything less than 100% enthusiasm for raw.
Poo-picking - one of the reasons we switched from kibble is because Woody was incredibly farty (and they really stank) and seemed to have permanent diarrhoea, including bits of mucous and even blood at times. On raw he's had pretty much rock hard poo, v small quantity, often white and crumbly and not remotely offensive, and hopefully helping with the emptying of the old anal glands (sorry!) too.
Cost? Depends a lot on where you get it from. I think we are spending about £60 a month on food which for us is A LOT. But I do buy it from the expensive end of the market and I'm going to give Manifold (thanks Bid) a go in an attempt to bring the cost down.
The 'ick' factor: Depending on how realistic you are about where your own meat comes from, it can be a bit of an eye opener to have a freezer full of duck necks and lamb ribs. I can't quite bring myself to go the whole paunched rabbit / pig-trotter / half a pigs head hog (terrible pun, sorry) because its just a bit too abatoir-esque for me. The sanitized version is to buy the prepared minces with bone in which I'm now completely chilled about.
Practicalities: you need a reasonable size freezer (if you're going to buy in bulk or get it delivered in bulk) and you need to keep on top of defrosting things. In practice this means for us, having a plastic box of defrosting meat resting on top of the cooker (or in the fridge) pretty much 24/7. And if you forget to take it out in time, you'll be falling back on Naturediet packs (which are apparently good quality - Woody likes them) or kibble or scraps.
You might also find it difficult to feed raw while you're away / camping. We just followed advice on here and switched to naturesdiet while we were away, and Woody didn't mind one bit.
Mess - if you're going to do the raw meaty bones / body parts thing, you're going to need somewhere for the dog to eat them. We haven't properly cracked this yet - its no problem if it's dry and they can go in the garden. Bit more difficult if your dog has lamb ribs for dinner and it's pouring outside so they've got to eat them in the kitchen. I know Bid has 'bone blankets' but Woody has a habit of dragging whatever he's chewing off the blanket and across the floor a bit. But then, if you've got a dog, your floor is probably not exactly spotless anyway!
Lastly, you might find yourself at odds with your vet or your other dog owning friends, because in some circles, feeding raw is still considered a slightly odd and possibly risky thing to do. Personally I think vets have a vested interest in kibble (the more expensive the better) and many aren't very well informed about canine nutrition. But the looks on my friends' faces when I described unpacking three polystyrene boxes of frozen raw meat and bones was a picture!
Reading through, I seem to have come up with loads of negatives and not many positives, but the positives are massive and the niggles relatively minor - at least for us.
If you fancy trying it, why not just buy some mince & maybe a few chicken wings and see what your dog makes of them and how you feel about it?
