Today, pudgy pups are becoming the norm in many American households. According to the Association for Pet Obesity Prevention (APOP), an estimated 56 percent of dogs are overweight or obese.

Since obesity can create a host of medical ailments—from diabetes and osteoarthritis to heart disease and cancer—it’s important to find the best dog food for weight loss to complement your pet’s weight-loss plan.

How to Put a Dog on a Diet


In order to get your dog on a weight-loss diet, you’ll need to calculate their calorie intake, determine their target weight, choose the best dog food for weight loss, establish a feeding routine and work toward reaching their target weight.

Calculating Your Dog’s Calorie Intake and Target Weight


For otherwise healthy dogs, most veterinarians will calculate the calories your dog needs with a maximum goal of losing 2 percent of initial body weight per week.

Depending on a number of factors, a loss of 0.5 percent of initial body weight per week can be used as the minimum desired rate of weight loss.

Your veterinarian will also calculate your dog’s target weight and determine the amount of time needed to reach this goal.

Then your veterinarian can suggest the best dog food for weight loss, explain how to calculate your pet’s daily calories and schedule regular weigh-ins. Often the weigh-ins will be scheduled every two weeks for the first two months of weight loss.

Once the target weight is achieved, a new feeding plan will be initiated with the best weight-management dog food to stabilize your dog’s body weight.


Choosing the Right Dog Food for Weight Loss


We all know that weight loss happens when calories in (food) are less than calories out (energy). We alone are responsible for what our dogs eat, and we have 100 percent control over the calories they intake. Prescription weight-loss diets are incredibly effective in the battle of the bulge.

Several components to look for in a weight loss diet include:

  • Nutrient density
  • High fiber, low fat
  • L-carnitine levels
  • Antioxidants


Nutrient Density

The value of choosing a diet formulated specifically for weight loss—and not “weight control” or “weight management”—lies in the diet’s nutrient density. There are two parts to nutrient density: 1) calories in a set serving of dog food and 2) nutrients in that same serving.

Diets formulated for weight loss in dogs are designed to decrease energy intake (measured in calories) so that weight loss occurs, while also maintaining appropriate nutrient levels and not inducing nutritional deficiencies.

If you simply feed less of a regular or weight maintenance food, your dog may not get the necessary nutrients, as these diets are nutritionally complete based upon a regular-sized portion, not a diet-sized portion.


Higher Fiber and Lower Fat

Diets higher in fiber and lower in fat promote satiety. A study by Royal Canin found that this combination helped prevent begging in 83 percent of the dogs in a weight-loss study. Weight-loss foods further fine-tune the fiber ratio of soluble to insoluble to promote weight loss.


Therapeutic L-Carnitine Levels 

L-carnitine is an amino acid that helps move more fatty acids into cells to be burned for energy, helping dogs to move and metabolize fat instead of storing it. Carnitine will be listed under the “Guaranteed Analysis” section of the food label, along with the amount.



Diets that are formulated for weight loss are often enriched with antioxidants that are clinically proven to increase energy, decrease inflammation and contribute to improved metabolism.

A study performed Hill’s Nutrition found that feeding the prescription weight-loss diet called r/d reduced dogs’ body fat by 22% in eight weeks. Look for these types of studies that prove that a canine prescription weight-loss diet does what it claims to do.


Creating a Feeding Routine for Your Dog’s Weight-Loss Plan


It’s important for you to work with your veterinarian to create a feeding routine that keeps your pup satiated while also on track with their weight-loss plan.

Here are a few tips you can follow to help your dog hit their weight-loss goals:

  • Measure out the exact amount of food as directed by your veterinarian
  • Feed smaller meals throughout the day instead of free-choice feeding
  • Do not allow access to other pets’ food or human food
  • Limit treats and stick to vet-approved treats

Some vet-approved treats include:

  • Carrot slices
  • Green beans
  • Cooked lean meat
  • Packaged low-calorie treats
  • Broccoli


Reaching Your Dog’s Target Weight Through Exercise


Controlling food and calories alone only gets us so far in a dog weight-loss routine. Weight loss in dogs depends on reducing caloric intake and increasing caloric expenditures (burning calories).

Talk with your veterinarian about your dog’s unique capabilities and needs before starting a new exercise routine.

At your dog’s weigh-ins, your vet will adjust their diet and exercise routine to cause a rate of 1-2 percent loss per week.

Many dogs lose weight in a stair-step fashion, losing quite a bit over a two-week period, and then not losing much over the next two weeks. Alterations in diet plans are not usually done unless weight has not changed at two sequential examinations.


Maintaining the Ideal Weight


After the desired target weight is reached, your dog’s body weight is monitored monthly to ensure that the ideal weight is maintained.

Just remember that even after the diet is over, approved treats should still only comprise less than 5 percent of the total caloric intake.

Weight management  is one of the most important areas to monitor  for  pet parent responsibilities.  As described in the article, being overweight can lead to Diabetes and Cardiac Disease in addition to many other significant illnesses.   Bella and I work hard to keep her weight within reason.    As she is getting older , it definitely has become harder.    When Bella gained 10 pounds I sought the advice of our veterinarian.   She helped me to determine caloric intake for Bella and suggested that I break up her meals to twice a day.    I was very impressed with this article because of the information that it contains.  Information that was on point with the information given to me by my  trusted veterinarian.
One of the major problems we had were treats.  I have to admit that Bella is a very spoiled  puppy and she gets treats often throughout the day.  I never considered the calories involved with the frequency of the “little” dog treats.
As suggested I began to substitute carrot chips and apple slices as treats.   Bella loves the “new” treats and has lost weight with the reduced caloric intake.     This is a great article full of suggestions and information to help you maintain a healthy weight in your dog.

Don’t forget to check out the banner/links to the various on line stores to the right of this page  (lap top) or beneath the article (smart phone).  There are traditional pet stores as well as well as  specialty stores for gifts that would make any pet parent ecstatic!  There is also a link to Amazon and Walmart where you can purchase anything that they sell.

We are delighted to announce a new affiliate agreement with  Embark Vet (DNA testing for pups)  this testing not only provides DNA testing but also genetic information on various propensities towards genetic illnesses that your pup might be prone to   based on their breed.   It is well worth the fee for all of the information that you get fro the finished report.    I ordered a kit and had my Bella tested.   I received a 16 page report answering all of the questions that I had about my service dog!   The great news s tat Bella has no genetic tendencies for the most common deadly diseases prone to Doberman Pincers, like  DCM..   This company provides one of the most complete genetic testing profiles that I have seen.  If you have questions – check out this site for report examples.

      I am sorry Mike, but I am not a nutritionist. I would suggest that you make an appointment with a nutritionist or a weight loss physician to discuss your plans. Good Luck and much success.
