Disclaimer: This is a starting formula to cover all dogs. If you notice your dog is above or below their desired weight, please adjust their food intake accordingly and wait 3-4 weeks before adjusting again. Activity is also a factor, so you may need to increase for a more active dog in the summer or a less active dog in the winter. Age can also play a factor in what is required per day. We do not recommend tubes be thawed past 4 days. If your pet cannot consume a 5 lb. tube within that timeframe, we do have multiple packaging options to choose from to accommodate them.
