What Makes It Different?
Diet dog food is different from traditional food because it comes with a formula that is lower in calories and usually higher in fiber to keep your dog full on smaller portions. It usually has a lot of fruits and vegetables with alternative carbohydrates like brown rice or sweet potatoes to make it healthier for your dog to eat every day. The protein sources come from lean meat like chicken, turkey, duck, fish, or lamb to support healthy muscle growth.
This is a step away from many traditional dog food styles that come packed with unhealthy carbohydrates and fillers. These things do very little for your dog from a nutritional standpoint, but they work to fill in the formula to make it look fuller to buyers.
Of course, all dogs need treats to be rewarded for good behavior. When your pal is on a diet, make sure you choose treats with few calories and try to keep up with how much you are giving your pal, so you are not overfeeding on treats. One good way to combine rewards and benefits is to use dental treats.
Since dog food can have dozens of ingredients and comes in wet and dry varieties, it’s a good idea to have set criteria in mind when you shop. This way, you can compare different brands with the same standards to ensure you’re going to buy the best one.
Healthier foods come with sweet potato or brown rice for their carbohydrate source over white rice or corn, and these two ingredients are more nutritionally sound than traditional ingredients. Sweet potatoes and brown rice are lower in calories per serving, and they bring a lot of additional nutrients to your dog’s diet when they eat their food.
Protein should be the first or one of the first ingredients on the label because this ensures the dog food has more protein from high-quality sources. Look for whole meat sources as well such as chicken, duck, turkey, or lamb without meat meals. The food shouldn’t have a lot of meat by-products either because these things aren’t as nutritious as whole meat sources.
Antioxidants can give you dog a boost of energy that encourages them to play and be active, and they also work to repair cell damage. Antioxidants come from a huge variety of food sources like blueberries, spinach, dark green leafy vegetables, fish, and more. Some brands have an antioxidant blend added right into to formula. They’re especially helpful for older dogs.
Food By Life Stages
You want to feed your dog food that is appropriate for their different life stages because they have different nutrient needs. In general, there are five formula categories you want to consider, and weight management is one of them. The five categories include:
- Puppy – Puppy food is great for dogs under a year old, and it has fat and protein ratios that keep your puppy growing at a steady pace. This food promotes joint and bone development.
- Adult – Adult food is great for age one to age six or seven, and it usually contains a good mix of fat and protein that promotes average activity levels without excess weight gain.
- Senior – Senior food has lower fat and protein content with higher fiber levels to help regulate digestion and maintain a proper weight at lower activity levels. Glucosamine is an important ingredient as well to support joint and bone health and flexibility.
- Active or Performance – Active or working dogs need food that has higher protein, antioxidants, and fat levels. These higher levels will help your dog maintain proper body conditioning and weight while giving them the energy they need to perform.
- Weight Management – If your dog starts to gain excess weight, weight management food can help them safely slim down. This food has lower fat and protein levels with higher fiber to help your dog feel full.
