Using this is still not helpful to someone like Labradorks who is starting out with a raw diet. Two marketing strategies that made the pet food industry a billion dollar industry was getting us humans thinking our dogs were like us and
1. Needed a fully balanced diet every day of their life, morning and night. (Which we now know this overload can cause strain on their bodily organs and subsequent organ failure etc...).
2.Needed carbohydrates.
Not only is a dog's metabolism not like humans their cognitive functioning is also not like human's! And even if there was a similarity with human's then the "cognitive" lull you describe in your first post occurring in afternoons for us humans is related to CARBOHYDRATES. Feeding raw especially PMR doesn't involve any carbs and BARF only should be a small percentage.
I had to remind myself this week that although I knew all this I was still thinking about making the morning and evening feeds not too different in amounts....and so when I realized I was still thinking about 'dogs feeding like humans" I was greatly surprised that altering this worked well. But it is a constant struggle to remind ourselves that dogs are not humans when it comes to feeding. Compare with wolves but don't compare with humans otherwise your on the slippery slope back to kibble.
