When your dog is prescribed non-steroidal anti-inflammatory drugs (NSAIDs) for joint pain or arthritis, your vet will likely recommend regular blood tests as part of their treatment plan. This monitoring might seem excessive, but it's actually one of the most important safety measures to protect your dog's health whilst they benefit from effective pain relief.
NSAIDs designed for dogs are generally very safe when used properly, but like all medications, they can occasionally affect major organs including the liver, kidneys, and digestive system. The good news is that most potential problems can be prevented or reversed when caught early through routine blood monitoring.
Understanding why these tests matter and what to expect can help you feel more confident about your dog's treatment plan and ensure they get the best possible care.

Why Dogs Need Special Monitoring on NSAIDs
Dogs process medications differently than humans, making them more sensitive to certain side effects from anti-inflammatory drugs. Whilst veterinary NSAIDs like Galliprant, Rimadyl, Metacam, and others are specifically formulated for canine use, they still require careful monitoring to ensure your dog's organs remain healthy.
These medications work by blocking specific prostaglandins that cause pain and inflammation, but prostaglandins also perform important protective functions throughout the body. They help maintain the stomach lining, support kidney function, and regulate blood clotting. This is why regular blood tests are essential to check that these vital systems continue working properly.
Most adverse reactions occur within the first month of treatment, but problems can develop at any time during long-term use. The key is catching any changes early, when they're most easily managed and often completely reversible.
What Blood Tests Reveal
A comprehensive NSAID monitoring panel examines several key areas of your dog's health. Liver function tests measure enzymes like ALT, ALP, and AST, which can indicate if the liver is under stress or showing signs of damage. These enzymes normally exist at low levels in the blood, but rise when liver cells are affected.
Kidney function is assessed through BUN (blood urea nitrogen) and creatinine levels. These waste products are normally filtered out by healthy kidneys, so elevated levels can signal reduced kidney function. Your vet may also check red blood cell counts and other markers depending on your dog's individual risk factors.
Common NSAID monitoring tests and what they check
| Test | What it measures | Why it matters |
|---|---|---|
| ALT | Liver enzyme levels | Early indicator of liver stress |
| Creatinine | Kidney waste filtering | Shows kidney function changes |
| BUN | Blood urea nitrogen | Another kidney function marker |
| Complete blood count | Blood cell numbers | Detects bleeding or clotting issues |
These baseline measurements help your vet establish what's normal for your individual dog. Every dog has slightly different normal ranges, so having their personal baseline is crucial for detecting meaningful changes over time.
When Blood Tests Are Needed
Before starting any NSAID treatment, your vet should run baseline blood work to ensure your dog's organs are functioning properly. This is particularly important for older dogs or those with existing health conditions that might increase their risk of side effects.
The initial follow-up blood test typically occurs 2-4 weeks after starting NSAIDs, as most adverse reactions develop within the first month of treatment. If these results look good, the monitoring schedule usually shifts to longer intervals based on your dog's age and health status.
Dogs over 10 years old generally need blood work every 3-6 months whilst on NSAIDs, as age increases the risk of organ dysfunction. Senior dog health checks become increasingly important for monitoring overall wellbeing in older pets.
Dogs with pre-existing conditions like kidney disease, liver problems, or heart conditions require more frequent monitoring, sometimes monthly initially. Your vet will create a personalised schedule based on your dog's individual risk factors and response to treatment.
Warning Signs Between Tests
Whilst regular blood work is essential, you also play a crucial role in monitoring your dog's wellbeing at home. Certain symptoms warrant immediate veterinary attention, even if your dog's next scheduled blood test isn't due yet.
Loss of appetite is often the first sign owners notice when dogs develop NSAID-related problems. If your normally food-motivated dog suddenly shows no interest in meals, contact your vet promptly. Similarly, vomiting, diarrhoea, or unusual lethargy should never be ignored in dogs taking anti-inflammatory medications.
When to contact your vet about NSAID side effects
Mild changes
Slightly reduced appetite or energy levels, mention at next appointment
Concerning symptoms
Loss of appetite, vomiting, diarrhoea, increased drinking or urination, stop NSAID and call
Serious signs
Yellow eyes or gums, severe vomiting, collapse, difficulty breathing, seek immediate care
Changes in drinking and urination patterns can indicate kidney problems, whilst yellow discolouration of the eyes or gums suggests liver involvement. These more serious signs require immediate veterinary attention, but fortunately they're relatively uncommon when dogs are properly monitored.
Making Blood Tests Less Stressful
Many dogs find veterinary visits stressful, but there are ways to make blood draws easier for everyone involved. Bringing your dog's favourite treats or asking if you can stay with them during the procedure often helps reduce anxiety.
Some practices offer early morning appointments when dogs are calmer, or separate quiet areas away from the main waiting room. If your dog is particularly anxious, discuss options with your vet. They may suggest mild sedation for blood draws or alternative scheduling arrangements.
Fasting isn't usually required for NSAID monitoring blood work, so your dog can have their normal breakfast before the appointment. This can actually help keep them more comfortable and cooperative during the visit.
Understanding Your Dog's Results
When your vet calls with blood test results, don't panic if they mention that some values are slightly outside the normal range. Laboratory reference ranges are quite broad, and small variations are often normal for individual dogs, especially if they're consistent over time.
What matters more is the trend, whether values are stable, improving, or gradually worsening. Your vet will compare current results to your dog's previous tests rather than just looking at whether they fall within the standard range.
If concerning changes are detected, your vet might recommend temporarily stopping the NSAID, switching to a different medication, or adjusting the dose. Most dogs return to normal quickly when problems are caught early through regular monitoring. If you notice any concerning symptoms or have questions about your dog's results, speak to your vet for guidance.
Supporting Joint Health Alongside Medical Treatment
Many owners find that joint supplements can work alongside veterinary treatment to support their dog's overall mobility and comfort. MedPaw's hip and joint supplement contains ingredients like glucosamine, chondroitin, and omega-3 fatty acids that may help maintain joint health over time.
When pain is well-controlled and joint function is supported through multiple approaches, it's sometimes possible to reduce NSAID doses or frequency. This can potentially reduce the need for frequent blood monitoring whilst still maintaining your dog's comfort and mobility. Always discuss any changes with your vet first.
Weight management, appropriate exercise, and physiotherapy can also play important roles in managing joint conditions. Discuss these complementary approaches with your vet to develop a comprehensive care plan that supports your dog's long-term wellbeing.
Planning for Long-Term Treatment
If your dog needs long-term NSAID therapy, factor the cost of regular blood monitoring into your budget from the start. Whilst the expense might seem significant, it's far more cost-effective than managing advanced organ damage that could have been prevented.
Some veterinary practices offer wellness plans that spread monitoring costs throughout the year, making budgeting easier. Others may provide package deals for dogs requiring frequent blood work, so it's worth asking about available options.
Keep a record of your dog's blood test dates and results, either in a notebook or on your phone. This helps ensure you don't miss scheduled monitoring and provides valuable information if you ever need to see a different vet or emergency clinic.
Regular blood monitoring allows dogs to safely benefit from effective pain relief whilst protecting their long-term health. By working closely with your vet and staying alert to potential warning signs at home, you can help ensure your dog enjoys improved mobility and comfort with minimal risk. Remember that joint supplements can complement veterinary treatment to support overall joint health, but proper medical monitoring remains essential for any dog on prescription anti-inflammatory medications.
How often does my dog need blood tests whilst taking NSAIDs like Metacam or Rimadyl?
Your vet will typically run baseline blood work before starting NSAIDs, then follow up after 2-4 weeks of treatment. After that, dogs over 10 years old usually need monitoring every 3-6 months, whilst younger healthy dogs may only need annual tests once stable on treatment. Dogs with existing health conditions may need more frequent monitoring, sometimes monthly initially.
What should I do if my dog stops eating whilst on anti-inflammatory medication?
Loss of appetite is often the first warning sign of NSAID-related problems and should never be ignored. Stop giving the medication immediately and contact your vet the same day. Other concerning symptoms include vomiting, diarrhoea, increased drinking or urination, and unusual lethargy - all warrant prompt veterinary attention.
Are the blood tests for dogs on NSAIDs expensive and how can I budget for them?
Whilst regular blood monitoring does add to treatment costs, it's far more cost-effective than managing organ damage that could have been prevented. Many veterinary practices offer wellness plans that spread monitoring costs throughout the year, or package deals for dogs requiring frequent blood work. It's worth asking your vet about available payment options to help with budgeting.
Can joint supplements help reduce how much NSAID medication my dog needs?
Joint supplements containing ingredients like glucosamine, chondroitin and omega-3 fatty acids may help support overall joint health alongside veterinary treatment. When pain is well-controlled through multiple approaches, it's sometimes possible to reduce NSAID doses, but you must never make medication changes without discussing them with your vet first.
What do elevated liver enzymes mean in my dog's blood test results?
Elevated liver enzymes like ALT, ALP or AST can indicate the liver is under stress, but don't panic if values are slightly outside normal ranges. Your vet will look at trends over time rather than single results, and small variations are often normal for individual dogs. If concerning changes are detected, your vet may adjust medication or recommend temporary breaks from treatment.
