Well, I looked at the flax seed thing like this: the casing has a toxic component. It's fine for most if it's ground. It grows on a plant much like Oats as far as I can tell. So, to me, after looking at it and where the experts place it in the food chain, it's a grain! The same with the eggs…it comes from a chicken. Will it give the same allergic reaction that chicken meat, broth would? And the veggies.
I don't necessarily believe that the veggies should be a staple. Especially as Zina did fine before I introduced the vetggies and fruit. BUT, I believe that they do have a nutritional component. Particularily fiber. When Zina had ear problems, the woman told me to mix Lavender oil and olive oil and put it in her ear. Excuse me, but isn't lavender a weed? Would that not give a further reaction? Wolves in the wild do eat fruits and veggies-even bark from the trees. If I leave compost outside, the coyotes will eat it.
Which brings me back to this, what EXACTLY do you feed your dog and in what percentages. What kinds of meats? How often? I do know this is your opinion, but that is what I am trying to gather-more info. I'm willing to try almost anything at this point as I have tried different methods of kibble, raw, mixed. She will start out great and then go downhill.
As for feeding yours fruits-especially apple, have you tried putting Peanut Butter on it to start? Once he acquires a taste, it may be different. Sounds like he doesn't like the first bite which is probably a different texture on his teeth than he is used to.
I feed a modified prey-model raw diet. I feed 80% meat/10% organs/10% bones, over time. I feed 2-3% of Magnum's ideal body weight, depending on how he's looking. It's usually about 1/2-pound a day. I feed chicken, turkey, lamb, beef/beef organs, venison, tripe, eggs, fish. I'm open to feeding other meats, if I can find them at reasonable prices (like buffalo, duck, veal, elk). Lots of people feed pork, but I don't, it doesn't agree with Magnum's tummy.
He's generally fed twice a day, once in the morning and once in the early evening. This morning he got about 2 ounces of ground chicken/frames and 2 ounces of ground beef/beef organs spritzed with some salmon oil. I feed ground food fairly often, that's why I said above that I feed a "modified" prey-model raw diet. I don't feel that feeding a big chunk meat offers any more nutritional benefit than feeding that same chunk of meat ground. Big chunks of meat, which I feed less frequently, do provide a workout/distraction and teeth-cleaning benefits.
I don't worry about fiber, as it is not an essential nutrient in a healthy dog's diet. I might reconsider if Magnum started having issues with, say, frequent diarrhea or constipation.
Wolves and coyotes may eat the things you mention if they can't find anything else and they're hungry, but from what I've read, they will not eat them if meat is available. I've also read that when wolves kill a ruminant, they will shake the stomach contents out before consuming the stomch.
I have tried putting peanut butter on fruit a number of times (I've even tried cream cheese and yogurt), Magnum licks off the "good stuff" and leaves the fruit, every time. Thanks for the suggestion, though.
