In most animals, the length of the small intestine is roughly 3.5 times body length - your small intestine, or that of a large dog, is about 6 metres in length. The small intestine is the longest section of the digestive tube and consists of three segments forming a passage from the pylorus to the large intestine:

Duodenum: a short section that receives secretions from the pancreas and liver via the pancreatic and common bile ducts.

Jejunum: considered to be roughly 40% of the small gut in man, but closer to 90% in animals.

Ileum empties into the large intestine; considered to be about 60% of the intestine in man, but veterinary anatomists usually refer to it as being only the short terminal section of the small intestine.

That's great, thanks Kay :)

Any idea how long it takes from the dog eating the meal to it pasing out the other end, average :) ?

The migrating motor complex is a distinct pattern of electromechanical activity observed in gastrointestinal smooth muscle during the periods between meals.
As studied in dogs and man, the cycle recurs every 1.5 to 2 hours and consists of 4 phases:

A period of smooth muscle quiescence lasting 45 to 60 minutes, during which there are only rare action potentials and contractions.

A period of roughly 30 minutes in which peristaltic contractions occur and progressively increase in frequency. Peristalsis originates in the stomach and propagates through the small intestine.

The phase lasting 5 to 15 minutes in which rapid, evenly spaced peristaltic contractions occur. In contrast to the digestive period, the pylorus remains open during these peristaltic contractions, allowing many indigestible materials to pass into the small intestine.

A short period of transition between the barrage of contractions in phase 3 and the inactivity of phase 1.

Guess what happens after that :D :D :D
