meat/protein

The problem with just about every greyhound I have ever seen eat is that they do not chew their food but just scoff it down. As such chunks of meat are going to be harder for the digestive system to break down into the protein components and the danger is that this will further reduce the required protein intake.

Finely minced meat, both red meat and chicken, plus soaked bread and a portion of cooked rice thoroughly mixed together with whatever additives you wish to add to that such as calcium, a vitamin mixture, a small portion of milk powder, and even a soft boiled egg and a heaped teaspoon of lard, would provide far better nutrition and more useable energy.

Then because the meat is finely minced and thoroughly mixed with the soaked bread the digestive juices would penetrate the food much easier to break it down into the components that are absorbed into the body to use.

Cheers,
