Pet Nutrition and Feeding Costs

How Much Should You Feed Your Pet?

Feeding guidelines depend on your pet's weight, age, activity level, and the caloric density of their food. Most dog food bags provide a feeding chart, but these are starting estimates — active dogs need more, while sedentary or older dogs may need less. Cats typically need 20 calories per pound of body weight daily. Overfeeding is the leading cause of pet obesity, which can lead to diabetes, joint problems, and shortened lifespan.

Premium vs. Budget Pet Food

Premium pet foods tend to have higher-quality protein sources, fewer fillers (corn, soy, wheat), and more digestible ingredients. While they cost more per bag, you often feed less per serving because the food is more nutrient-dense — potentially narrowing the real cost difference. Our calculator helps you compare the true monthly and yearly cost across different food brands and serving sizes.
