Dry Dog Food vs Wet Dog Food (Pug)

The majority of dog owners often prefer dry food for reasons of convenience and price. For example if you are buying canned wet food, 60-90% of what you are buying is actually moisture (water). Due to this you will quite often find that you need to feed them twice as much food as you would if the food was bought dry. Grain gluten and other protein gels may be used in wet dog food to create artificial meaty chunks, which look like real meat. 

Dry food contains 6-10% moisture by volume
Canned food contains 60-90% moisture.
Semi-moist foods have a moisture content of 25-35%.

Try to look at the back of packaging not just the pretty logo. Cheaper brands tend to contain cereals like corn, wheat, barley and ash, all the good stuff that your dog would never eat in nature and that passes right through its bowels with little to no nutrition. Also something to note is these ingredients are quite often the source of most allergies in dogs and cats and bowel irritations. If you happen to be the owner of a brachycephalic dog you will probably notice when eating these foods that contain considerably more corn and wheat that can become much more flatulent (fart or gas) - See more at: http://www.sweetpeapugs.co.uk/pug-feeding.html#sthash.nX277ZeV.dpuf
