My small dog is overweight. What OTC food can help her lose weight?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 9 years and 2 months old | 9 lbs

Would you please recommend OTC dog food for weight loss? Scribbles has always struggled with her weight. She weighs 9.2lbs. We tried prescribed food, unfortunately she tends to vomit. We've tried a few from pet stores, no luck. Perhaps we're part of the problem too. I give her treats (when she goes potty on pee pads. She's been a mopey dog ever since she was spayed years ago. It's like it took her puppy/doglife away. Very sad.... Any recommendations would be helpful and appreciated. Karrey

You can try science diet senior light formula with small bites as an option or try one of their prescription formulas such as metabolic. Purina also makes a prescription type called OM and has severe reduced calorie over the counter options. You will need to really regulate the amount of food she receives in a day more than anything. You can switch her potty treat to Cheerios--they are small and have few calories to add up. For a 10# dog to lose weight, you are looking at feeding her a little less than 1/2 cup of food a day total. It is not much, so you want to really measure it with a measuring cup. You can try to increase her activity level and play with her and add in walks to also help burn calories
