Scout was spayed on Saturday morning and we've been instructed by the vet to only take her on short walks with no running around for 7-10 days. She's about 10 months old and 55lbs, so we have been feeding her 3 cups a day of puppy food. But since she's not getting much exercise in the next week, how much should we feed her? 1.5 cups a day? 2 cups a day?
