I wouldn’t do it by ounce. Count his calories. A normal dog should have 25-30 cals per lbs. every food has a different calorie content and canned foods tend to be a lot lower cal than kibble because they contain so much water.
What cans are u finding that are 14oz? ?
Anyway look at the cans cal content and do the math that way. So since your dog is a little chubby maybe set him at 20 cals per pound at first. So just 400 cals a day and then go from there
