Try adding in canned pumpkin to his diet, and cutting back on dog food. If you cut back 1/2 cup kibble, add a 1/2 cup canned pumpkin. Make sure to use pure pumpkin with nothing else added (don't use the pie filling type). This really helps your dog feel full without adding too many calories. My rottie adores having it added to his food. To him it is more exciting then the kibble. All the people I know who have tried it, have been really happy with the results!
Good luck!
