I used to feed veg & rice with my dogs food but after lengthy reading and research I now only feed what lots of others do on here which is prey drive ---- consisting of no veg or rice.
Tripe is an excellent food as it contains so much that a dog needs.
Here's a little excerpt re tripe and re veg.
---------------------------------------------------------------------------------------
Carnivores, dogs and cats cannot convert vegetation into nutrients within their own stomach, but when they eat tripe, they receive nutrients from grasses and grains that have been already processed naturally by a 'four stomach system' of ruminants, hence they are receiving nutrients in the way nature intended as a natural process of the food chain .
Tripe is the stomach (not stomach contents) of ruminating animals. These animals such as cattle, sheep, deer and goats, are classified as being four-footed, cloven hooved, cud chewing mammals with a stomach that consists of four chambers, each with it's own function.
The four chambers of the stomach are known as the rumen, reticulum, omasum & the abomasum.
The food the animal eats (i.e. grass, hay) is swallowed unchewed & passes into the rumen & reticulum where it is then regurgitated, chewed & mixed with saliva.
It is again swallowed & then passed through the reticulum & omasum into the abomasum, where it is then further broken down by the gastric juices, amino acids & other digestive enzymes.
Abomasum tripe is also seen, but with much less frequency, due to its glandular tissue content.
