Well, firstly, I would have liked to have known my dog is "allergic" to chicken haha. It would have saved me probably one thousand dollars in vet bills. There's a hell of a lot more chicken in a chicken quarter than there is in any commercially prepared food.
Raw is awesome when it's done correctly. I would rather see someone feed Beneful than feed raw haphazardly. It takes a lot of knowledge to understand why you have to feed the things you do and be able to evaluate your dog's response to the diet. You have to be good at food safety, too. Improper food handling is a good way to make the humans in the house sick, and maybe even the dog.
Dogs fed raw shed more bacteria in their saliva and their stool than dogs fed kibble, too, so you will have a greater bacterial load in your house. For this reason, raw food isn't recommended when the dog is going to be around immuno-compromised people, like very young children and the elderly. You should be washing your hands before eating anyway.
Read up on vitamin deficiency or excess symptoms. Be aware of your dog's normal water intake, normal activity level, normal behaviors, etc and make note of diet changes. For example: I switched to feeding grass-fed beef liver and my dog began draining the water bowl. After this went on for three or four days, I determined he probably had excess Vitamin D from the liver change and his fish oil supplement. I cut out his fish oil supplement and his water intake returned to normal in two or three days.
There's a greater choking hazard with raw food, too. The dog may try to gulp the food down and you may have to provide assistance; yes, this means you need to watch your dog eat and know the signs of choking and know how to deliver a doggy heimlich. I have had to shove my hand into my dog's mouth on multiple occasions because he got some meat stuck between his teeth and couldn't swallow it all the way. If your dog resource guards his food, raw is not the way to go. You have to be able to help your dog.
There's a risk for intestinal parasites with raw food, especially when feeding wild game. My dog's heartworm medicine is also an intestinal parasite preventative so I don't worry about that, and really, all meat sold in the US should be parasite free. Freeze wild game for at least 2 weeks to kill parasites, but preferably a month or longer, before feeding it to your dog. NEVER FEED FRESH SALMON. Salmon and salmonids must be frozen for at least two months before feeding due to "Salmon poisoning".
Freezing only stops the growth of bacteria, it does not kill bacteria. Ground meat has a much higher bacteria load than a slab of meat. Theoretically, bacteria only exists on the portion of the meat that is exposed to air, so the inside of a slab of meat is bacteria-free. Theoretically. Ground meat is exposed to air all over during the grinding process. Meat from animals raised and slaughtered in typical USA confined feeding operations and commercial slaughterhouses is expected to have a much greater bacteria load than meat from animals raised by independent farmers and slaughtered in a smaller facility. Avoid supermarket meat as much as you can.
I recommend testing your dog's blood chemistry before the switch and then at least once a year to be sure the diet isn't doing anything super funky to your dog's body.
For my 30 pound dog, raw works out to costing less per day than feeding him Orijen kibble. When I last checked, Orijen worked out to $1.17/day and raw worked out to $1.12/day (with chicken).
There is no hard scientific evidence that raw food is better for the dog than a kibble diet. However, it doesn't take a genius to know whole, fresh food is better than pre-prepared convenience food.
