Weight Loss Supplements for Dogs: Types, Safety Considerations, And Choosing The Right Supplement

Reviewed by - Dr. Jeremy, Doctor of Veterinary Medicine (DVM), MS

 

The short answer: If your dog needs to lose weight, supplements alone won't do it. The most effective approach is a vet-guided plan combining calorie reduction, daily exercise, and targeted supplements. The best-studied ingredients for canine weight loss are L-carnitine (boosts fat metabolism), dietary fiber (promotes fullness), and probiotics (supports gut-driven metabolism). Always get a vet assessment before starting any supplement.

 

Howdy, pet lovers!

Did you know that obesity is considered a disease of the 21st century? This issue doesn’t only affect humans; our furry friends are also at risk.

 

Obesity is more than just excess weight; it’s a condition associated with various diseases, co-morbidities, and significant healthcare and social costs.

 

If you think you can easily regulate your dog’s body weight, think again. Achieving and maintaining a healthy weight for your dog requires your active involvement. A successful approach combines a nutritious diet, regular physical exercise, and well-chosen supplements.

 

Today, we’ll delve into weight loss supplements for dogs. Let’s take a closer look!

 

Disclaimer: No supplement alone will reduce your dog’s body weight. Weight management is a complex process that requires commitment. Always consult with a veterinarian for personalized advice regarding your dog’s supplements!

 

How to tell if your dog is overweight (BCS explainer)

Before reaching for a supplement, the first step is understanding whether your dog actually has a weight problem and how serious it is. Many pet owners are surprised to learn that what looks "normal" for their dog may already be in the overweight range.

Veterinarians define dogs as overweight when they weigh 10–20% above their ideal body weight, and obese when they exceed that ideal by more than 20%. Because ideal body weight varies so much by breed and build, these percentages matter more than the number on the scale. A Chihuahua and a Great Dane can both be obese at very different weights.

 

The Body Condition Score (BCS): The Most Reliable Way to Assess Your Dog's Weight

 

The tool vets use most often is called the Body Condition Score, or BCS. It runs on a scale from 1 to 9:

• 1–3 (Too thin): Ribs, spine, and hip bones are clearly visible. The dog looks gaunt with no fat coverage.
• 4–5 (Ideal): Ribs are easy to feel but not visibly prominent. There is a visible waist when viewed from above, and the belly tucks upward when viewed from the side.
• 6–7 (Overweight): Ribs are harder to feel because of a fat layer. The waist is less defined, and the belly tuck is minimal or gone.
• 8–9 (Obese): Ribs cannot be felt at all without pressing. There are obvious fat deposits over the spine, base of the tail, and neck. The dog has no visible waist and the belly may actually hang downward.

Your veterinarian will assess BCS at every routine checkup, but you can also get a reasonable sense of it at home.

 

According to statistics from 2018, around 56% of dogs are overweight or obese; 36.9% of dogs in the United States were overweight, while 18.9% were classified as obese. Additional data show that Minnesota, Nebraska, and Michigan have the highest percentages of obese dogs.

 

The COVID-19 pandemic has altered our lifestyles, and our dogs' habits have changed as well. A study conducted through a survey between 2020 and 2022 revealed that, out of 309 dogs, 35.3% were overweight, including 2.3% who were obese.

 

In simple terms, obesity refers to the accumulation of excess body fat, leading to increased body weight.

 

Both obesity and being overweight can lead to numerous health issues. For starters, these conditions can shorten a dog's life expectancy. Overweight dogs are also at a heightened risk for problems such as hypertension, heart disease, diabetes mellitus, cancer, urinary stones, and complications related to anesthesia and surgery.

 

Additionally, overweight dogs often become less mobile, which can lead to osteoarthritic issues and arthritis. Furthermore, many systemic diseases can arise due to excess weight.

 

Role of Weight Loss Supplements

 

 

Weight loss supplements are widely recognized in human medicine, often sparking controversy due to numerous brands marketing them as miracle cures for quick weight loss. In veterinary medicine, the concept of weight loss supplements for dogs is relatively new, with limited options available on the market.

 

Most weight management strategies for pets primarily revolve around specially formulated pet foods. However, when combined with a proper diet and regular exercise, weight loss supplements can play a supportive role in a dog's weight loss journey. These supplements can help address specific aspects of weight management, such as promoting satiety, enhancing fat metabolism, and supporting overall health.

 

However, it’s important to stress that these supplements are not a magic solution. They should be considered part of a broader weight management plan that includes a balanced diet tailored to your dog’s specific needs, along with regular exercise to promote overall health.

 

Types of Weight Loss Supplements

 

Let’s see the different types of supplements that can support your pup in maintaining a healthy weight and the science behind it.

 

Dog Fiber Supplements for Weight Loss

 

 

Fiber is an essential component of a dog's diet, playing a crucial role in digestive health and weight management. By promoting feelings of fullness and aiding in regular bowel movements, fiber can help dogs maintain a healthy weight while also supporting overall well-being.

 

According to studies, a high-protein, high-fiber (HPHF) diet can improve satiety in dogs. In the study, 15 dogs were fed an HPHF diet, while a control group of 27 dogs received a high-protein, medium-fiber (HPMF) diet with the same caloric density. The results showed that the percentage of weight loss was greater in the HPHF group compared to the HPMF group.

 

In simpler terms, fiber helps dogs feel fuller for longer, which can reduce their overall calorie intake. It slows down digestion and promotes a sense of fullness, allowing dogs to stay on a calorie-reduced diet without feeling hungry.

 

Dog Carnitine Supplements for Weight Loss

 

L-carnitine is an amino acid that plays a key role in fat metabolism and energy production. It helps transport fatty acids into the mitochondria, where they are burned for energy. This ingredient can enhance a dog’s ability to convert fat into usable energy, promote weight loss, and support overall energy levels during physical activity.

 

One study investigated the effect of L-carnitine on feed intake, body weight and composition, and Basal Metabolic Rate (BMR), in Labrador Retrievers fed high-calorie diets. The trial lasted 15 weeks, divided into an 8-week weight gain phase followed by a 7-week exercise phase.

 

The results showed that pets fed high-calorie diets can benefit from L-carnitine because it leads to a decrease in food intake and an increase in basal metabolic rate, helping to prevent weight gain. L-carnitine also showed significant weight loss, particularly at higher doses.

Omega-3 Fatty Acids for Dog’s Weight Support

 

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two very important Omega-3 fatty acids. 

 

Disclaimer: It’s important to note that not all omega-3 sources contain these specific fatty acids; for example, plant-based omega-3s do not provide significant amounts of EPA and DHA. Therefore, choosing a high-quality omega-3 supplement derived from marine sources (like fish oil and Jope Hip & Joint Dog Chews) can help ensure your dog receives the full range of benefits associated with these essential fatty acids.

 

These healthy fatty acids have anti-inflammatory properties that can help reduce inflammation associated with obesity.

 

Owner assessments indicate that dogs fed these fatty acids show a significantly improved ability to rise from a resting position after six weeks of omega consumption. Additionally, after 12 and 24 weeks, dogs demonstrated enhanced walking power. Omega fatty acids can also help prevent further joint cartilage degradation, preserving cartilage depending on the stage of osteoarthritis.

 

You might be wondering how this relates to weight loss. Improved mobility allows your dog to engage in daily physical activities more easily, which can help them lose weight effectively.

 

Similarly, in humans, increased mobility can facilitate more frequent and intense exercise, contributing to weight management and overall health improvements. When individuals can move comfortably, they are more likely to engage in activities like walking, jogging, or exercising, all of which are essential for burning calories and maintaining a healthy weight.

Dog Probiotics for Weight Loss

 

A healthy gut microbiome is crucial for effective weight management in animals. Probiotics can improve digestion and nutrient absorption, ensuring that dogs receive the maximum benefits from their food. These supplements help maintain a balance between good and bad bacteria, which can regulate metabolism, reduce inflammation, and support the weight loss process.

 

Recent research on probiotics investigates how probiotics, particularly Enterococcus faecium IDCC 2102 and Bifidobacterium lactis IDCC 4301, influence gut microbiota to reduce obesity The results showed that these probiotics effectively reduced body weight, lipid accumulation, and systemic inflammation in cases of high-fat diet-induced obesity. These probiotics improved microbiota balance and metabolic processes, enhancing energy utilization and restoring stable eating behavior and glucose tolerance in the canine model studied.

 

This is very promising!

Herbal Supplements

 

Certain herbs, such as green tea extract and garcinia cambogia, are sometimes included in weight loss supplements for dogs. Green tea extract is believed to boost metabolism and aid in fat oxidation, while garcinia cambogia may help suppress appetite. Psyllium husk can be beneficial for weight management by promoting satiety, as it takes up space in the stomach similar to other fiber supplements. Additionally, spirulina is a nutrient-rich supplement that supports overall health and may aid in weight management.

While green tea extract is frequently discussed in weight management, caution is advised due to its caffeine content, which poses potential risks for dogs.

 

It’s essential to consult a veterinarian before introducing any herbal supplements to ensure their safety and efficacy for your dog.

 

Disclaimer: Exercise caution with herbal supplements, as some dogs can have adverse reactions. We strongly advise consulting with a veterinarian before giving any to your dog!

 

Safety Considerations

 

Regardless of the supplement and its intended purpose, we always advise pet owners to consult a veterinarian before starting any regimen. Not all supplements are suitable for every dog, and their effects can vary significantly from one dog to another. Your veterinarian can provide recommendations based on your dog's specific needs, age, and health status.

 

Weight loss supplements can lead to side effects, including gastrointestinal upset, diarrhea, and vomiting—especially with fiber or probiotic supplements. Additionally, herbal supplements may cause allergic reactions or other adverse effects. Be sure to monitor your dog closely for any signs of discomfort or unusual behavior.

 

Choosing the Right Supplement

 

 

Here at Jope, we consider a product high-quality if it meets the following criteria:

 

• Formulated by a veterinarian or a nutrition expert.
• Backed by studies that support its claims. Without this evidence, you can't be sure that the chosen strain effectively supports your pup's health.
• Uses the correct dosage as indicated in the studies.
• For probiotics, stability is crucial. As living microorganisms, their potency decreases over time. Each strain has its own stability, and there are methods to extend their viability.
• Made in the U.S. in a GMP-compliant and NASC-approved facility.
• Contains a limited amount of inactive ingredients.
• Undergoes third-party testing to ensure the correct quantities of active ingredients.
• Trusted by veterinarians, who are meticulous about the products they select for their clinics.
• Offers responsive customer service for your questions.

 

Before incorporating any supplement into your dog’s diet, remember to:

 

• Consult with a veterinarian for personalized advice.
• Choose a reputable supplement brand.
• Introduce it gradually.
• Monitor your dog’s reaction.

 

Conclusion

 

Weight loss supplements can be beneficial for maintaining a healthy weight, but they shouldn't be relied upon alone. The most effective approach combines a balanced diet, regular exercise, and carefully selected supplements.

 

Be sure to choose a supplement with your veterinarian and develop a strategy that suits both your and your dog’s lifestyle.

FAQ

1. What is the best weight loss supplement for dogs?

The best-studied weight loss supplements for dogs are L-carnitine and dietary fiber, both of which have clinical evidence specifically in canines. L-carnitine supports fat metabolism by transporting fatty acids into cells to be burned as energy, while fiber promotes fullness and reduces overall calorie intake. No single supplement works in isolation; the most effective results come when supplements are used alongside a calorie-controlled diet and regular exercise, under veterinary guidance.

 

2. My dog needs to lose weight - where do I start?

Start with a vet visit before changing anything about your dog's diet or adding supplements. Your vet will rule out underlying medical causes of weight gain (such as hypothyroidism or Cushing's disease), assess your dog's Body Condition Score, and calculate a safe daily calorie target. From there, the core plan is portion control, a higher-fiber or higher-protein diet, increased daily activity, and, where appropriate, targeted supplements to support the process.

 

3. Does L-carnitine help dogs lose weight?

Yes, L-carnitine has clinical evidence supporting weight loss in dogs when used as part of a calorie-restricted diet. A study in Labrador Retrievers found that dogs supplemented with L-carnitine showed decreased food intake, increased basal metabolic rate, and greater weight loss compared to unsupplemented dogs particularly at higher doses. It works by transporting long-chain fatty acids into the mitochondria, where they are converted into usable energy rather than stored as fat.
