What does it mean if my dog's BUN levels are high on a blood test?

We recently got some blood work done for our dog, and I noticed that her BUN levels came back higher than normal. I'm not sure what this could indicate, especially because she seems fine at home. Could this be a sign of something serious, or are there other factors that might cause elevated BUN levels?

Answer

If your dog's BUN (Blood Urea Nitrogen) levels are higher than normal, it might indicate an issue with the kidneys, but other non-serious factors can also cause elevated BUN levels.

  • Kidney dysfunction or disease
  • Dehydration
  • High protein diet
  • Heart disease
  • Gastrointestinal bleeding

Blood Urea Nitrogen is an important test that helps assess kidney function by measuring the amount of nitrogen in the blood derived from urea, a waste product of protein metabolism. Elevated BUN levels can sometimes suggest that the kidneys aren't functioning properly, but they can also be influenced by other factors such as diet, hydration status, or even stress. Because your dog appears fine at home, it might not be urgent, but it's important to discuss these results with a veterinarian to understand the underlying cause and determine if further testing or treatment is needed.
