Hi, I am by no means a vet or anything but I just had to take some weight off my epileptic girl, at 3 yrs old she was 97lbs and fat, faaaattttt, lol, but with her seizures I had to be careful about the way I went about a diet plan for her, so we went to a grain free kibble, she gets fed twice a day, but I cut each feeding to 1/2 and the other 1/2 of her feeding was thawed or fresh green beans. We started in April at 97lbs and 8 months later on the 19th of this month we weighed in and she is 65lbs. It is a huge difference and she is so much more active and can breath better now. I hope it helps, good luck with your venture, and someone said something about a better food with no fillers, that helps as well
