How much should I feed my bull terrier

Ruckus

Hi I have a 5 month old bull terrier named ruckus I am wondering if I am feeding him enough I give him 3/4 of a cup of dry grain free kibble with a lil canned wet food mixed in twice a day but he acts like he's still starving is that enough or to much and he picked up this horrible hobbit of eating my other dogs poop sometime right out of his butt -_- and he has been horrible  to house break will even poop and pee in his bed in his cage I love him to death and would never get rid of him but he's not making life easy lol and help would be greatly appreciated

He sure is handsome

Every dog is different but for example my 4 month old bulllies are eating 3 times a day

Every serving is one cup dry 2 big spoons of beef or chicken or a spoon of each plus a tablespoon of cottage cheese

So yes I would feed him more

My 6 month old is eating 2 cups of kibble with a spoon of yogurt at 6:30 in the morning.

He eats 1/2 kilo of meat with veg + sups at 5:00 in the evening.

He would also eat a lot more if i allowed him to. 

He is a very active dog who gets a lot of exercise.
