Did you know that dogs can suffer from high cholesterol, just like people? While it might not be the first health issue that comes to mind for our furry friends, elevated cholesterol levels can signal underlying medical problems. As a pet parent, understanding the symptoms, causes, and treatment options can help you keep your dog healthy and thriving.

⚠️ What to Watch For

High cholesterol in dogs, also known as hyperlipidemia, often doesn’t show obvious symptoms early on. However, in some cases, it can contribute to more noticeable health issues. Here are some signs that could indicate your dog might be dealing with high cholesterol:

  • Fatty deposits under the skin (lipomas or xanthomas)
  • Vomiting or diarrhea
  • Decreased appetite
  • Lethargy or low energy levels
  • Cloudy or greasy appearance in the blood during lab tests

Because these symptoms overlap with other conditions, it’s important to consult your veterinarian for an accurate diagnosis. Often, high cholesterol is discovered during routine blood work or when investigating other health concerns.

🔍 Possible Causes

High cholesterol in dogs can stem from various factors, including diet, genetics, and underlying medical conditions. Here’s a closer look at the common causes:

  • Poor diet: High-fat diets or excessive human food can contribute to elevated cholesterol levels.
  • Obesity: Overweight dogs are more prone to hyperlipidemia.
  • Breed predisposition: Certain breeds, such as Miniature Schnauzers and Shetland Sheepdogs, are genetically more likely to develop high cholesterol.
  • Medical conditions: Diseases like hypothyroidism, diabetes, pancreatitis, and Cushing’s disease can lead to high cholesterol.
  • Medications: Some drugs, such as corticosteroids, may increase cholesterol levels as a side effect.

In some cases, the condition may be idiopathic, meaning no specific underlying cause can be identified.

✅ What You Can Do at Home

If your dog has been diagnosed with high cholesterol, there are steps you can take to support their health and manage the condition effectively:

  • Switch to a low-fat diet: Work with your vet to find a high-quality, low-fat dog food that meets your pet’s nutritional needs.
  • Encourage regular exercise: Daily walks and playtime can help your dog maintain a healthy weight, which is crucial for managing cholesterol.
  • Avoid table scraps: Many human foods are high in fat and can worsen your dog’s condition.
  • Provide healthy treats: Opt for low-fat treats like carrot sticks, green beans, or apple slices (no seeds).
  • Follow your vet’s advice: If your veterinarian prescribes medication or supplements, be sure to administer them as directed.

Consistency is key when managing high cholesterol. Small, daily changes can make a big difference in your dog’s overall health and well-being.

💡 When to Call a Vet

It’s always better to be proactive about your dog’s health, especially when dealing with a condition like high cholesterol that may not show obvious symptoms. You should contact your veterinarian if:

  • Your dog seems lethargic, has a decreased appetite, or is vomiting frequently
  • You notice fatty deposits under their skin
  • Your pet has been diagnosed with a condition like hypothyroidism or diabetes, as these can increase the risk of high cholesterol
  • You suspect their diet may be contributing to health issues

Your vet will likely recommend blood tests to confirm the diagnosis and identify any underlying causes. Early detection and treatment can prevent complications and improve your dog’s quality of life.
