Weight Loss In Older Dogs: When To Worry

Most owners will inevitably observe changes in their dogs as they enter their senior years. While some of these changes are typical, others may raise concerns, such as abrupt weight loss. In this article, our veterinarians in Santa Rosa will address weight loss in older dogs and when it warrants concern.

When Your Older Dog is Losing Weight

Weight gain in older dogs is more common than weight loss, but this is not always the case. When your senior dog experiences sudden or gradual weight loss, it can cause concern. Generally, two main factors contribute to a dog losing weight and muscle mass as they enter their golden years.

  1. Your dog has an underlying health condition, and weight loss is a symptom of it.
  2. Your dog requires a new diet at their age.

When is Weight Loss in Older Dogs a Concern?

When older dogs experience weight loss often indicates an underlying health condition. These conditions encompass liver/gallbladder disease, dehydration, dental problems, kidney disease, heart disease, diabetes, cancer, and arthritis.

Your veterinarian should diagnose and address each of these issues. Most of these root causes manifest alongside other symptoms alongside weight loss.

To best support your senior dog with excess weight loss, document all their symptoms and schedule a vet examination in Santa Rosa.

What to Feed an Old Dog That is Losing Weight

If your veterinarian does not have a medical diagnosis for your dog's weight loss, ask them about your dog's current diet and the amount of protein, fat, and fiber they are getting. Your vet may be able to suggest a new diet/meal plan to get your pup back on track to a healthy weight.
