How do You Put a Dog On a Diet?

Whether it is a small, medium, or a large dog breed, putting your pet on a diet requires some work. The most important step is to choose the right dog food for weight loss. You will also have to create a feeding routine, exercise your dog, and calculate your dog’s calorie intake and target weight. Remember, it takes time to get your dog back to the ideal weight.

Choose The Right Dog Food for Weight Loss

Dog foods for weight loss are sometimes as calorie-dense as regular dog kibble. But it features different kinds of calories and significantly fewer fat ingredients.

When choosing the right dog food for weight loss, it’s not enough to read reviews only. Make sure to pay attention to the following:

  • Nutrient density – best measured via calories per cup
  • Low fat / high fiber – fibers will compensate for the absence of fat and fuel your dog energy. Plus, according to Royal Canin and University of Liverpool study, this ratio helps preserve lean body mass during weight loss.
  • L-carnitine – because it is known for its beneficial fat burning effects
  • Antioxidants – to support healthy oxidative balance in your dog

Create a Feeding Routine

If you are inexperienced in creating a feeding schedule for a dog, consult your veterinarian. The following rules will help you create an efficient feeding routine:

  • Eliminate free-choice feeding. Instead, feed smaller meals during the day
  • Make sure that each meal contains the exact amount of food as suggested on the food label or by your veterinarian
  • Don’t feed your pet anything else or make sudden switches to other foods
  • Use only vet-approved treats such as cooked lean meat, carrot slices, green beans, and broccoli

Keep Your Dog Fit Through Exercises

Feeding your dog meals based on a weight-loss recipe is not enough. You have to incorporate regular physical activity for your dog to promote weight loss. Again, let the veterinarian assess your dog’s needs and capabilities to make the most efficient exercise routine that easily fits in your time schedule.

Calculate Your Dog’s Calorie Intake and Target Weight

In the best-case scenario, your dog will lose 2% of his initial body weight per week. Fortunately, a perfect weight is known for every breed. For rescue dogs, the ideal weight is calculated by factoring in their size.

With the help of your veterinarian, you will be able to calculate:

  • your dog’s target weight,
  • the most optimal time to reach it, and
  • Take your pet’s daily calorie needs and divide it by the number of meals

How much should I feed my overweight dog?

Make sure to feed your overweight dog at least two meals per day at approximately the same time. Frequent meals will bust its metabolism rate and help it burn more calories. You will be able to see the first results in two weeks. The diet is successful if your dog loses 0.5 to 2 percent of his starting body per week or 2 to 8 percent per month.

How do I know if my dog is overweight?

Humans have a BMI to check whether they are overweight. Dogs have BMI of their own, and it is called body condition score. Thanks to the Association for Pet Obesity Prevention, you can also check ideal dog weight ranges.

There are some signs that can help you know your dog is overweight. If it sleeps longer than usual, moves slower, or breathes heavier when walking, the chances are that it packed a few extra pounds.

What Causes Dogs to Gain Weight?

While there are many reasons why dogs become overweight, the most common ones include:

  • Eating too much food – eating too many nutrient-dense meals a day disrupts the balance between energy intake and output. The unused calories get processed and stored as fats.
  • Not enough exercise – regular exercise maintains the same energy output. In other words, it burns calories. If your dog doesn’t burn calories, they will end up as fat under its skin.
  • Your dog suffers from a chronic condition – there are some chronic conditions that cause dogs to gain weight, such as Cushing’s disease and hypothyroidism. If you notice sudden weight gains make sure to visit your veterinarian to eliminate the possibility of these diseases
  • Your dog is genetically-predestined to gain weight – some breeds are more prone to gaining weight than others, including Cavalier King Charles and American cocker spaniels, Cairn terriers, Shetland sheepdogs, Labrador retrievers, beagles, basset hounds, dachshunds, and rough collies.
