If you have an older dog and you notice that senior dog losing weight but still eating, you might be worried. You’re probably asking yourself: “Why is my senior dog losing weight but still eating?” Don’t panic. This is a common concern in senior dogs and usually indicates something important about their health.
In this guide, we’ll explain the main causes, warning signs, health risks, and what you can do to help your senior dog maintain a healthy weight.
Understanding Weight Loss in Senior Dogs
Sometimes senior dogs eat normally but still lose weight. This is different from a dog refusing food. If your dog continues eating but their body weight drops, it could indicate nutritional, metabolic, or medical issues.
Interesting Fact: Studies show that older dogs can lose up to 20% of their body weight in a year if underlying health problems are not addressed.
Common Causes of a Senior Dog Losing Weight But Still Eating
Here are the main reasons your senior dog might be losing weight even though they eat normally:
1. Hyperthyroidism or Other Hormonal Issues
Senior dogs can develop hormonal disorders that speed up metabolism. This makes them burn calories faster than they consume, leading to weight loss despite normal appetite.
2. Diabetes
Diabetes can cause weight loss because the body cannot properly use sugar for energy. Dogs may eat more, but still lose weight because nutrients are not absorbed correctly.
3. Dental Problems
Even if your dog eats, painful teeth or gum issues can prevent proper chewing, leading to malnutrition and weight loss over time.
4. Kidney or Liver Disease
Organ dysfunction affects nutrient absorption and metabolism, causing your senior dog to lose weight even while eating.
5. Cancer or Tumors
Unfortunately, some cancers in older dogs lead to unexplained weight loss despite normal appetite. Early detection is key.
6. Malabsorption or Gastrointestinal Problems
Conditions like inflammatory bowel disease, pancreatitis, or parasites can prevent proper nutrient absorption, leading to weight loss.

How to Help a Senior Dog Losing Weight But Still Eating
1. Vet Evaluation
The first step is always a thorough vet checkup. Blood tests, urine tests, and physical exams help identify the root cause.
2. High-Quality Senior Dog Food
Feed a diet that is:
- High in protein to maintain muscle

- Rich in vitamins and minerals
3. Supplements if Needed
Vitamins, omega-3 fatty acids, and probiotics can help older dogs absorb nutrients better. Only give supplements recommended by your vet.
