From my research, if it has to be Grain Free I think you may have a hard time finding a food that low in calories. I’m in a similar predicament, my 8 yr old chocolate lab is 84 lbs and the vet recommends 78 lbs as her ideal weight. Dr. Tim’s does make a 5 star food that is only 286 kcal/cup but it does contain grain (it’s called Metabolite). In my opinion, for grain free it’s better to go with a good quality/higher protein food which is slightly higher in calories (say 350-380) and feed a little less. Or cut down the dry kibble and mix in wet food which is much less calorie dense (ie. a whole can of wet food generally has the same number of calories as only one cup of dry kibble.) This is what I’m doing for my Heidie and she’s down 2lbs in the last month or so. I like the Wellness Core reduced fat mentioned above mixed with any variety of 5 star canned products (one of my favorites is the Weruva human style ones.)
Just my 2 cents…Good luck! 🙂
