Dog Digestive System
It is essential to know that your dog is not a human, but a carnivore. At the same time it is not as exclusively dependent on meat as for instance a cat is. From a physiological point of view, dogs can best be classified somewhere in between a carnivores and an omnivores, with some very profound carnivore preferences.
It serves no purpose to argue whether the correct classification should be “carnivore” or “omnivore”. The important thing is that you should fully understand the huge differences between the ways a dog is “constructed”, compared to the way a human is. Those differences call for a complete adjustment of what you should think is right for your dog. If something is right for you or for another human, it might actually be very, very wrong for your dog. If something is not good for you, it could be a very healthy thing for your dog.
When you look at a dog’s mouth, you will see that it has fang teeth for grabbing, holding and tearing. The front teeth are there to scrape meat off bones. The incisors are small “saw teeth” which are there to grab and hold. The big incisors are there to cut, acting as a pair of scissors. And the molars behind are there to crush. The jaws are fairly long enabling the fang to grab quite large objects. The muscles that control the jaws are some of the most powerful muscles in the dog’s entire body.
The rest of the dog’s digestive system is pretty much similar to any carnivore as its stomach secretes all sorts of enzymes and acids to digest raw meat and fiber that constitutes the diet of your dog.
The further construction is also quite similar to us as it has a large intestine connected to a small intestine which ends at rectum, which in turn opens outwards as the anus. What we have to understand here is that your pet has a very sensitive digestive system which needs to be maintained by a balanced diet.
