What is your opinion of the advantages/dangers of feeding raw?
I personally feel that raw is the absolute best thing for ANY dog. Feeding a proper raw dieg helps with digestion issues, promotes healthy teeth and gums, restores skin and coat health, improves overall health, makes poop cleanup a breeze, and give peace of mind that you're doing the best for your dog.
I don't really see any dangers when done right. I'm careful to feed bones of appropriate size, meaning I don't give them bones without enough meat attached to make them chew a bit. I also freeze fish before feeding.
Also, would it help to do things like freeze, soak in hydrogen peroxide, or in grapefruit extract to kill bacteria?
I feel more comfortable freezing salmon before I feed it, but even this is probably not necessary. I definately would not soak it in anything to kill bacteria. They are carnivores, they are designed to handle any bacteria raw meat could throw at them. I feed all the meats as is, right from the grocery store.
How about searing the meat?
Searing the meat will kill bacterias on the outside, but these bacterias are not harmful. It will also kill a lot of the nutrients, so the tradeoff of killing the harmless bacteria makes it not worth it to me. Just feed it as is.
There are a lot of ways of feeding raw, barf, pmr, etc. I personaly feel that a carnivore should be fed as such, so I eliminate all plant matter and feed nothing but meat, bones, and organs.
