I have obtained the minimum daily requirements for nutrients for my 2 dogs. I have a freeze dryer and I want to make my dog some food. Knowing the MDR for the dog how to I mix up the dog food so that a 4oz scoop of it for the little dog has the MDR in it as well as a 16oz blob of it for the big dog. Is this even possible to make it that generic.

    $\begingroup$ I’m voting to close this question because it has nothing to do with chemistry, per se. $\endgroup$ – DrMoishe Pippik Feb 21 at 20:49
  • $\begingroup$ If the MDR for each nutrient for the large dog is 4 times the MDR for each nutrient for the small dog, then you just give the small dog the 4 oz measure, and the large dog the 16 oz measure. This would be the case if you currently give both dogs the same commerical food, and they're fine with it. OTOH, if the two dogs require different formulations (e.g., puppy chow for the small dog, or "small breed" chow for the small dog), then obviously you would need different formulations for your own homemade chow. $\endgroup$ – theorist Feb 21 at 20:55
  • $\begingroup$ Or is your question instead about how to achieve homogeneity with a mixture? In that case, you would need to blend thoroughly with an electric mixer (perhaps a commercial-grade one, depending on how much you are making). But as to how you know you've achieved homogeneity, perhaps someone with specific experience in preparative chemistry can comment. $\endgroup$ – theorist Feb 21 at 21:02
  • $\begingroup$ Thank You. I will formulate for the small dog then give the larger dog "n" times the amount given to the smaller one. $\endgroup$ – E Purdy Feb 22 at 1:55
