Yes, the vitamin E and fish oil sold for humans is the same for dogs. The amount in the multivitamin tablet isn't enough.

The fish oil provides an essential fatty acid that is largely missing in even the best dog's diet, raw or manufactured, so supplementing it is important for all dogs. The vitamin E is added because it helps the dog's body metabolize the fish oil.

I have no problems with multivitamins as a nutritional "safety net" to supply missing nutrients. I take one myself. But I don't give one to my dogs. I'd rather spend those dollars on things I know they need more--like the fish oil and E...along with a varied diet that includes multiple protein sources.

So here's what I'd like to see you do to fine-tune your raw feeding:

1. Substitute a third of the chicken you're currently feeding with some other protein source. You can "rotate" in turkey, beef, pork, cooked eggs, canned fish, or anything else you can find. By the way--what chicken parts are you feeding now? Leg quarters? Whole chickens?

2. Continue to pay attention to the poops. If you add some boneless meat (say, a hunk of pork shoulder) you'll need to adjust the "boniness" of the chicken. I think chicken backs are just about the perfect dog food--they have lots of soft bones in them, they are super-cheap, and they are just right for mixing with some boneless meat in a meal.

(the amount of bone in the diet is largely responsible for the firm--but not rock-hard--poop consistency that raw-fed dogs have.)

3. Feed organ meats, liver or kidney, several times a week---up to 5-10% of the diet. But start this EXTREMELY slowly. Start with a piece of liver the size of your pinky fingernail. Then gradually increase the amount you feed. Too much organ meat fed at one time, especially to a dog unused to it, WILL cause diarrhea, I guarantee it. Organ meats provide a lot of nutrients that are not available in muscle meat. They are a must-have, IMO.

4. Stop focusing so much on the veggies as an "important" part of the diet. They are fine to feed some--and they do provide some additional vitamins---but not to the exclusion of the more important animal-source proteins in the diet. Vegetable matter should not make up any more than 5-10% at most. Also--any vegetables you feed your dog need to be "processed" in some way to make the nutrients available. Cooking, freezing, or pureeing are all possibilities. Raw vegetables will pass right through the dog and come out the other end unused because unlike humans, dogs cannot digest cellulose. So you have to do a little "pre-digesting" for them in order to make any plant-based food a suitable source of nutrition.

(this is why many people seek out "green tripe"...which is the partially digested vegetable matter left inside a cow's stomach. Dogs instinctively love this stinky mess. You can accomplish the same thing by freezing vegetables until they are mush, or putting them in the Cuisinart and blending them to pulp.)

Leafy greens and berries will give you the most nutritional bang for the buck...but mine also like occasional scraps of carrot, broccoli stems, peas, apple, sweet potato. But again, any of these plant foods are a very small "side dish" to a diet that is very-much meat based.

Hope some of this rambling helps.
