Senior dog losing weight despite eating. Is it her food or health?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Female | spayed | 155 lbs

My 13 yr old dog still eats lots of her normal food. She's a healthy weight, about 50-60lbs for a Labrador. But she's been getting thinner and more gaunt. She's on an adult dog food, would it benefit her to switch to a senior dog food?

Hi there and thank you for using pet coach to address your concern. The food probably wont make much of a change in her weight gain, as this may be primarily a metabolic problem, not necessarily the food itself. I would also be concerned that something systemic such as liver or kidney disease could be the cause. I would recommend having a veterinarian examine her so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
