dogs certainly can and do bloat on the raw diet, especially if they overeat (can happen if you have more than one dog eating together and one snitches from the others). there is also now a suspected DNA marker for bloat and what you feed then would make little difference.
the two most important factors for bloat are 1. body type and 2. first degree relative that has had bloat. and these are simply correlations, not causes. nobody really knows the cause.
the OP asked has anyone fed raw for ten years or more? my dog's breeder has been feeding raw for several generations. she has dogs that have lived to over 13 years of age that were weaned on raw. she was my mentor in learning how to raw feed.
i'll pass on to you the most basic guidelines she passed on to me:
1. feed a variety of meats and fish
2. keep it simple. feed what is locally available and cheap
3. feed only human grade meats
4. buy in bulk to save when there are sales (invest in a chest freezer, it will pay for itself quickly).
5. develop relationships with suppliers and have standing orders with them (see keep things simple).
6. don't sweat it. dogs have been eating raw bones for centuries.
7. try to keep your bone/meat ratio fairly close to what they would get if they were eating whole prey.
8. beef hearts, eggs, cottage cheese and yogurt are fantastic foods for dogs, in moderation.
9. don't over supplement. less is more. fish oil and kelp powder should do it.
10. never, ever defrost rmbs in a microwave. you could partially cook the bone and then it would be dangerous. cooked bones splinter.
11. beware of weight-bearing bones, they can crack your dog's teeth. stick with non-weight bearing bones like wings, necks, ribs, etc. in chickens you want to get young fryers whose leg bones are still soft.
as i've posted here many time before, i keep it easy by having a relationship with one supermarket meat department that expects to hear from me once a month. i order a couple of cases of whole chickens, three cases of beef hearts, two cases of turkey necks, a case of pork necks, some ribs and pork shoulders if they're on special (i never spend more than .99 a .lb and i try to keep it to .69).
the meat dept. cuts everything up or packages everything in 2 lb. portions, individually wrapped. i pick it up, it goes directly into the freezer, and then i defrost a few days worth in the fridge at a time. i often feed it frozen solid.
there should be no need to prepare meals.
i also buy some cans of salmon or mackerel and occaisionally feed with yogurt or cottage cheese, whole egg and shell, and kelp and fish oil. maybe i'll add ground leafy veggies to this once a week or once every two weeks, to keep him regular (pork neck bones can be constipating).
i also feed beef liver and hamburger on sale once in a while. and sometimes i'll just walk into the local supermarket and see what they have on special that i don't usually feed.
it's really very easy when you just hand the dog the contents of a package and let him deal with it.
you should see results in less than two weeks.
