From Zoomies to Gray Whiskers: When Your Pet Needs Bloodwork
West Buckeye Veterinary Hospital
One minute you have a puppy chewing everything in sight. Somehow, a few years later, that same dog has a gray muzzle and strong opinions about bedtime.
Pets move through life stages faster than we do, and their veterinary care changes along the way.
Bloodwork is a good example. A young, healthy pet may only need it in certain situations, while an older pet may benefit from more regular testing. A pet with an ongoing medical condition may need an entirely different schedule.
At West Buckeye Veterinary Hospital, we look at the pet, not just the calendar.
What Does Bloodwork Help Us See?
A wellness exam gives us important information about your pet’s heart, lungs, skin, teeth, weight, joints, and overall condition. But we cannot see kidney function or count red blood cells with a stethoscope.
That is where laboratory testing comes in.
A complete blood count checks red blood cells, white blood cells, and platelets. A chemistry panel looks at values related to organs and metabolism, including the kidneys, liver, blood sugar, proteins, and electrolytes.
Depending on your pet, we may recommend additional testing such as a urinalysis or thyroid test.
Puppy and Kitten Years: Bloodwork Is Usually Based on Need
Young pets already have a busy veterinary schedule. Exams, vaccines, parasite prevention, nutrition, and development take center stage.
Bloodwork is not automatically necessary at every appointment.
We may recommend it if your puppy or kitten has symptoms that need investigating. Repeated vomiting, diarrhea, poor growth, unusual tiredness, weakness, or loss of appetite are examples.
Another common time is before anesthesia.
If your pet is scheduled for a spay, neuter, or another procedure, pre-anesthetic bloodwork can help us identify certain issues that may not be obvious during a physical exam.
Adult Pets: Creating a Health History
Once your pet is an adult, routine bloodwork can help us create a record of what is normal for them.
That matters because every pet is a little different.
Imagine that your dog has bloodwork at age three, five, and seven. Instead of looking at the age-seven results by themselves, we can compare them with earlier numbers.
If something is starting to shift, that history may help us spot the trend.
Some healthy adult pets may have bloodwork every year. Others may follow a different schedule. We consider age, breed, lifestyle, medical history, and previous results.
Senior Pets: Gray Hair Is Cute, but It Comes With More Monitoring
Senior pets often need a little more detective work.
Dogs and cats can hide health changes remarkably well. Kidney disease, diabetes, liver problems, thyroid disease, and anemia can all begin before a pet looks seriously ill.
Watch for subtle changes at home.
Is your dog draining the water bowl faster? Is your cat losing weight even though dinner still disappears? Is your pet sleeping more, asking to go outside more often, or becoming less interested in activities they used to enjoy?
Tell us.
For some senior pets, bloodwork every six to twelve months may be recommended. Pets with existing medical conditions or medications may need testing more often.
There is no single age when every dog becomes senior. Larger dogs generally reach that life stage sooner than smaller dogs.
When Your Pet Is Sick, the Routine Schedule Goes Out the Window
If your pet is not feeling well, we may recommend bloodwork even if they recently had routine testing.
Symptoms such as repeated vomiting, diarrhea, poor appetite, weight loss, increased thirst, increased urination, weakness, pale gums, collapse, or significant lethargy can all be reasons to take a closer look.
Bloodwork may show dehydration, anemia, changes in blood sugar, organ-related abnormalities, or other clues.
Sometimes we need additional tests after that. Bloodwork is often the beginning of the investigation, not necessarily the end.
Medication Can Change the Timeline Too
Pets taking certain long-term medications may need regular bloodwork.
The reason varies. We may be watching organ values, blood cells, electrolytes, or checking whether treatment is working the way we expect.
Your veterinarian may recommend testing soon after starting a medication, after changing the dose, and then periodically once your pet is stable.
Even if your pet feels fantastic, those rechecks can still be important.
Why Test Before Anesthesia?
Anesthesia is another time when we may recommend bloodwork regardless of your pet’s age.
A physical exam helps us evaluate your pet, but laboratory testing gives us information we cannot see from the outside.
If a result is unexpected, we can decide whether the procedure should move forward as planned, whether we should adjust the anesthetic approach, or whether another test is needed first.
Normal results are helpful too. They give us more information and create another point of comparison for the future.
How Often Should Your Pet Have Bloodwork?
The answer changes as your pet changes.
A healthy puppy may need testing before a procedure. A healthy adult may benefit from periodic baseline bloodwork. A senior pet may need more frequent screening, and a pet with chronic disease may need regular monitoring.
At West Buckeye Veterinary Hospital, we can help you figure out where your pet fits right now.
If you are not sure when your dog or cat last had bloodwork, ask us at the next visit. We can review their history and recommend a schedule that makes sense for their current stage of life.
