My favorite is written by Dr. Pitcairn.
A nutrition book is a GREAT idea -- but ...
*smile* that's why there is CHOICE. I don't like Pitcairn -- and he's been around for years. Vet's, for my peace of mind, don't take much nutrition in vet school -- so that doesn't set them up for me as a an authority here. I prefer a canine nutritionist like either Monica Segal or Sabine Contreras. Both of them are very good (and have vet approvals out the ying yang).
Jettababy please don't think I"m bashing you -- LOTS of folks like Pitcairn and he is well-respected, I'm just not among them. I just think it's funny how incredibly diverse something like an innocent question about home-cooking can become, and honestly ALL folks who home cook typically do way way way better for their dogs than the *average* person who doesn't. You know what goes into what you make - you know what the quality is ... right there you're doing well for your pet.
Redlegos -- the answer to how much is going to vary completely by the individual dog. Even two dogs of the same size don't always need/use the same amount of food. Breed has a TON to do with it.
I home cook for Luna and Tink -- Tink is a pug and *should be* about 16.5 pounds. We have the devil's own time adjusting her weight. Luna, at 31 pounds, if FINALLY where she should be, but I have the worst time keeping weight *on* her.
Luna literally eats *more than* three times what Tink does. It's a pure difference in metabolism in their breed make-up. (and this is one of the reasons why you see so many fat pugs)
So you don't feed them "all they want" and there is no magic formula for how much they should eat. Start them on something like 1/4 to 1/3 cup (assuming they are around 8-10 pounds?) twice a day.
Weigh them before you start ... and then weigh them every week or every two weeks for a month. If you see them gaining, back off on the food a bit. If you see them losing, add a bit more food.
MEASURE. Be consistent. If you don't measure it you won't be able to adjust it. I use a measuring cup and literally keep it in the fridge on the container of dogfood. USE THE SAME ONE -- (sorry, this is the voice of bitter experience here -- it's the only way to ensure you do this consistently).
I go by a basic recipe but I vary it widely. I use a ton of different veggies, not the same ones over and over. This is where you either have to go with a pretty rigid recipe by a well-known nutriitonist or vary your recipe all over the place (including all different veggies from parsnips to kale to orange/white/green/all colors veggies). simply because in order to balance the diet you can be 1) really precise or 2) really varied so you catch the different minerals, etc. in the variety (much as we feed our own human selves).
You will need to supplement with calcium at a minimum -- some use eggshell, some use bonemeal (food grade NOT garden grade), and some use sea calcium (I use Animal Essentials calcium)
HOWEVER -- be cautious. Since you've got one you suspect may, in truth, have a food intolerance (and honestly I agree with Myra -- that sounds SO much like flea allergy dermatitis and vets are sometimes going to miss that) you likely should -- to maximize what you are trying to do -- do a food trial FIRST. I know you have wrestled with skin problems for a long, long time!! I applaud your effort to do something positive!!
an "elimination" or trial diet is different -- it is literally just TWO ingredients. That's all. Usually a meat and some veggie. Preferably you want to go to something "novel". Literally something they've never had before.
An elmination or trial diet does not need to be 'balanced' -- you'll only feed it for 3-6 weeks alone and then you will begin "adding" ingredients to see what provokes a bad reaction.
You could start with something like whitefish and mashed potato -- to be honest, your best bet would be to again seek the help of an expert. Simply to help you work your way thru it.
But you have to be rigid -- that means no treats, no extras -- you have to monitor every single thing that goes in their mouth and guidance for that is way more than I can give you in a post like this. But you have to avoid anything he's eaten in the past or you won't be able to rule out what it isn't. In other words if you try to do an elmination diet of chicken and rice and he doesn't do any better on it, you won't know if it is because he "didn't do well on cooked food" or whether it's because chicken and/or rice was part of the problem.
But if you do an elmination diet of something like ... lets say peas and sweet potato (because you couldn't find a meat that was an easily obtainable novel protein so you used peas) ... and you are TRULY rigid -- if he's not one whit better in 3 weeks, then it's probably NOT food. Does that make sense?
But if you let family "cheat" and slip them treats (which might have wheat, beef, soy, chicken, etc. etc. etc. in them) then you won't know a thing after all your effort.
