How To Keep Your Dog’s Weight Down

Feeding your dog more protein and fewer carbohydrates (or calories) is the first step in keeping your pet’s weight down. The truth is the rapport of fat, carbohydrates, and protein is more important than the number of calories. Some people opt for a diet low in protein, but that is a terrible mistake.

Many foods for overweight dogs are rich in carbohydrates but low in everything else. Losing weight is quite baffling then. Dogs need lots of protein to build a lean body and muscle, while carbohydrates have no actual roles.

Foods rich in dietary fiber do not make such an excellent choice for dogs either. You might think that fiber will help your dog eliminate more often. It does, but it will not help your pet drop a few pounds. Besides, too much fiber will inevitably affect nutrient absorption.

Grains represent a popular source of dietary fiber. In other words, grain-free low-fat dog food should be a top priority. It is usually low in carbohydrates, but it has plenty of protein. Just make sure it does not have too much fat.

While not always recommended, making your pet’s low-fat high protein dog food yourself could work because you know exactly what goes in. Lean meats should represent the primary source of protein, while low-fat dairy and green vegetables will add to the number of nutrients.

If fat can be separated, take it off. Also, the skin should be removed. Stay away from high-fat foods, such as pork, beef, or lamb.

When it comes to fats, your dog needs the right ones. Omega 3 and 6 fatty acids will help, and they are quite healthy.

Other ideas to consider include:

  • Reducing your pet’s serving size
  • Measuring everything your pet eats
  • No longer feeding your dog treats and snacks under the table
  • Weighing your dog every week
