I feed a varied diet, mostly 4Health kibble (one of the very very few dog food companies that actually makes food with a proper Calcium to Phosphorus level for large breed puppies and dogs), some raw when it presents itself (failed kits, whole eggs, failed chicks, butchering scraps, leftover fruits and veggies just starting to wilt, & leftover bones), and a lot of leftovers from my own meals (as well as many products about to expire such as dairy, meats, bread, grains, etc). There is almost always something left on my plate. I don't see any allergen, poop, or any issues related to food out of the many dogs I've raised. It also completely removed almost all wastage to feed this way and no wild animals are attracted to my trash
Everything has already been licked clean by a pack of dogs.
If you're going to feed just raw though, you really really do need to research and a lot. Well beyond what this forum is going to offer you. Dogs have died due to imbalanced and inappropriate raw diets. Not just died but died horribly. Diseases caused by nutrition imbalances can be extremely horrific, like deformed limbs on puppies or organ failure horrific which to me isn't worth it. I'd rather not risk it. Vets react the way they do to it because so few people know what they're doing when they get into it and they constantly see a barrage of these people when their feeding inevitably goes very south and still refusing to accept that the food is to blame when the vet tries to explain it.
It requires a lot of very careful planning and organizing and even maths since you need to keep ratios steady. It also helps if the dog you're feeding it came from a line of dogs that have been raised on it. Comparing to our rabbits, some come from long lines of pellet feeders. If you suddenly switched to all forage feeding (even gradually) you may see gut issues, parasite issues (they were from long lines of animals never - or very rarely - exposed to parasitism so would not have any inherited defenses against such), and you very may experience nutrition issues as well depending on your sources. It all becomes a careful balancing act and at least with rabbits we have mineral spools to help make up for what we missed. This applies to more than just rabbits. Goats too have issues with this as well as humans (all vegan raw diets in humans have been also problematic when not carefully balanced and supplemented).
I feed the way I do because it ensures proper nutrition without sticking my dog with GI issues later if things should ever happen to change (feeding a dog the same food its entire life can also be bad and result in serious gi issues if you should ever need to change it for any reason, variety is the spice of life anyway) Those of you who have changed your own diets in your lives might have run into this aswell. Eating mostly junk and then deciding to try healthy vegetables or fruits and then getting sick? Your body was trained to reject the good stuff.
