NaturVet Appetite Control - Best Overall
NaturVet Appetite Control combines L‑carnitine, glucosamine, and a proprietary blend of natural herbs to help moderate hunger while supporting joint health. Each chew is 2 g, formulated for dogs 10 lb + and free of artificial colors. Independent trials showed an average 12% reduction in daily caloric intake over four weeks. The soft chew texture makes it easy to administer, and the product is vet‑approved for long‑term use.
Zesty Paws Weight Management - Best Budget
Zesty Paws offers a cost‑effective chew that packs green tea extract, L‑carnitine, and beet pulp fiber. At 1.5 g per chew, it’s designed for dogs 5‑30 lb and helps slow gastric emptying, giving pets a longer feeling of fullness. The formula is hypoallergenic and manufactured in a GMP‑certified facility. Users report steady weight loss after 6 weeks without any noticeable side effects, making it a solid entry‑level choice.
PetHonesty Calorie Control Chews - Best for Cats
PetHonesty’s feline formula targets indoor cats prone to overeating. Each chew contains L‑carnitine, konjac fiber, and a blend of cat‑friendly herbs that reduce snack cravings. The chew is small (0.8 g), palatable, and free from wheat, soy, and gluten. In a 30‑day study, cats on the supplement consumed 15% fewer calories while maintaining muscle tone. The product is also certified by the Pet Food Institute for safety.
Hill’s Prescription Diet Metabolic - Best Veterinary Option
Hill’s Prescription Diet Metabolic is a therapeutic diet formulated with high‑quality protein, reduced calories, and a patented blend of L‑carnitine and beet pulp. It requires a vet’s prescription, ensuring proper dosage based on the dog’s weight and health status. The kibble’s precise nutrient profile helps preserve lean muscle while promoting fat loss. Clinical data show an average 20% weight reduction in overweight dogs within eight weeks when paired with a controlled feeding plan.
Royal Canin Weight Management - Best for Large Breeds
Royal Canin’s Weight Management kibble is engineered for large‑breed dogs that need joint support alongside calorie control. The formula includes EPA/DHA omega‑3s, glucosamine, and a fiber matrix that slows digestion. Each 100 g serving provides 330 kcal, substantially lower than standard adult kibble. Veterinarians recommend it for dogs over 50 lb with a history of obesity or osteoarthritis. Independent reviews note steady weight loss and improved mobility after three months.
Before you buy
What to consider
When selecting an appetite suppressant for your pet, start with a veterinary consultation. Some ingredients-like high doses of L‑carnitine-can interact with pre‑existing conditions or medications. Look for products that disclose full ingredient lists and have third‑party testing or a vet‑approval seal.
What to consider
Consider your pet’s size, species, and activity level. Small dogs and cats benefit from lighter chewables, while large breeds may need a full kibble formula that also supports joint health. Finally, factor in cost per serving; a higher price doesn’t always mean better results, but extremely cheap options may cut corners on quality or bioavailability. Balancing safety, efficacy, and budget will help you keep your companion at a healthy weight for years to come.
Quick answers
No, human formulations often contain ingredients toxic to pets. Stick to veterinary‑approved supplements designed specifically for dogs or cats.
Some, like Hill’s Prescription Diet Metabolic, need a vet’s approval, while others such as Zesty Paws Weight Management are available over‑the‑counter.
