Depends on the food and on his shape. You will just have to monitor him. As a pup he can stand to have a bit of chub on him but by 9 months you need to make sure he is slim or get him slim if necessary.
Mine get less than that. I feed James Wellbeloved.
Toddy, age 8, weight 7.5kg gets 90g of kibble per day, plus a bit of fish and turkey and a few treats.
Snifter, age 11, weight 9.5 kg gets 110g kibble per day plus the extras Toddy gets.
If you are going according to guidelines on the food you should probably cut down. They are notorious for being over-generous. But, as said above, your primary guide has to be your pug's own shape.
