Hello all, New to the forum. I have a 3 year old sheltie named Smoky and we got her from the Shelter a year ago. We love her to death. She is about 14" tall at the shoulder and weighs 17.2lbs. The vet said she is overweight so I am looking for guidance. I have The Hills Science Diet Sensitive Stomach formula we feed her. Looking for guidance on how much to feed as we would like to see her lose 2 to 3 lbs. Currently feeding 1/3 cup twice daily. As far as exercise, she loves exertion and I bike her at full sprint around 20 min per day and also walk her again at night for about the same amount of time. Just want to see her be at optimum weight and avoid health issues down the road. Any advice greatly appreciated.
