High Triglycerides in Dogs: Ask About a Fasting Recheck
PARTNER Editorial TeamIf your dog's blood test shows high triglycerides and the sample was taken after breakfast, tell the vet when your dog last ate. Triglycerides can rise after a meal. That detail can affect how a single result is interpreted, but it does not explain every high value.
Reconstruct what happened before the draw
Write down the last meal, including the time, food and any extras. A treat in the car or a snack used to give a tablet is easy to forget. Include medications or supplements, and note anything you are unsure about. Then ask which value was high: triglycerides, cholesterol, or both. VCA's hyperlipidemia overview explains the role of sample timing and other health conditions in evaluating high blood lipids.
| What you remember | Useful detail to share |
|---|---|
| Breakfast before the appointment | Time, approximate amount and type of food |
| Treat or chew on the way | Time and what it was, even if it was small |
| Medication given with food | Medicine, dose, time and what was used to give it |
Get instructions for your dog before changing anything
If the clinic wants a fasting sample, ask when to stop food, whether water is allowed, and how to handle each scheduled medication. Ask what to do if the appointment is delayed or someone accidentally gives a treat. If your dog has diabetes or needs medicine with food, mention that before withholding a meal or changing the medication routine. Our blood test preparation guide covers the practical questions to ask the clinic.
Ask what a repeat result would change
If triglycerides are still high in an appropriately prepared sample, the vet may look for underlying conditions or medication effects. MSPCA-Angell's clinical review describes why follow-up and management depend on the overall findings. Ask when the repeat is needed and who will explain the result. A single result is not enough information to pick a new food or adjust a prescribed diet on your own.
