Yes sure they go after the soft easy to chew and digest stuff first. That does not mean it is the best of the animal as a food source. And I could not care any less about a yahoo group of peoples preferences. Excessive amounts of organ meat is not good for your dog. It is your choice but your dog may suffer from your preference.
"The digestive enzymes that are so touted as being beneficial, are only helpful to the herbivore while it is alive, since they need and have evolved to have them in their gut to help digest plant matter, and extract the 'good' from it, since the proteins are low quality. A ruminant's digestive enzymes have no benefit for a carnivore, since carnivores as a rule do not eat the stomach contents of prey, and have their own evolved digestive enzymes and probiotics that assist in digestion and assimilation of meat, the digestible constituents in bones, and fat.
Yes, its true, dogs - and wolves - do not eat the contents of the stomach. They shake the digesta out, and eat the stomach itself, except in the case of very small prey.
Tripe is just meat, plain and simple, And, if you check it out alongside other meats in the USDA Nutrient Database, its not a particularly high quality meat. It has value, yes, as a body part, and part of variety, but shouldn't be fed to extremes.
Its singular value is that its supremely stinky, and most dogs go wild over it. So, sicky and aged and other dogs that need encouragement to eat, or eat more, or even to try something new, will often eat it, or meat/organs 'marinated' in it, even if they refuse other foods."
I am over joyed no more horse poo!
