Points for Consideration

Digestibility  -

for example the TLC dog product has an  overall digestibility of 83% which means that he can eat a more natural dog product with less human food and has the added benefit is smaller, firmer shit, which makes cleaning (orally or my the master) easier.

Texture -

Dog food with near human food texture

This includes Vegetarian dog food such as

• Sample UK and US products These have little taste, their texture can be a bit vile (but you get used to it)
• Dried dog biscuits, treats. Be careful here - Dogs teeth are stronger that a humans dogs!!!

Beyond here you need to be confident that your dog has a strong digestive system, and a good constitution.
Otherwise he might have an upset tummy or needs to visit Accident & Emergency.
