Usually if dogs are given raw foods only occacionally they go through detox very often as supposed to dogs going on raw once and staying on raw. But, that being said, some dogs have problems with the raw diet, especially raw meaty bones, because the marrow in the bones is very high fat and that can potentially give them diarrhea. So far we have had no problems and they have been on it for a month today. The really interesting thing I have noticed is that my older dog, Gus (dachshund, 4 yrs, so not old at all, but not a puppy anymore) his teeth were horrible, and the vet wanted to have some dental work done to remove the tartar, guess what? The tartar is almost all gone, after a month, because he has been using his teeth the way nature intended, chewing and gnawing on bones. I am exstatic, especially since I didn't feel comfortable with anesteshia. As a bonus, the dogs are loving their meals…they have had numerous ground meats, chickenwings, necks and turkey necks, as well as gizzards and hearts (eek) and the other day they had sardines ( I know it isn't raw but that is all I had and is a acceptable substitution for raw fish ..on occasion), they went to town, as a matter a fact, Otis was trying to lick the stainless steel off of his food bowl, of course they also eat veggies, kelp and fruits, no grains though...dogs never did eat grains in the wild..
I had over the years fed my other dogs raw for years and once I got pregnant with my 4 year old started giving them kibble again out of fear of foodborne illness contamination and lets face it, out of convinience, but I am glad I took the plunge again and I know the dogs are too.
