Johnson Ranch Animal Clinic
Your pet can tell you plenty without saying a word. You know when they want dinner, when they are bored, and when they are ready to head outside. What they cannot tell you is when something inside their body has started to change.
That is one reason bloodwork can be such a useful part of veterinary care.
At Johnson Ranch Animal Clinic, we may recommend bloodwork when a pet is perfectly healthy, when something seems off, before anesthesia, or while we are monitoring an ongoing condition. How often it makes sense depends on your pet’s age, health history, medications, and previous results.
Here is what San Tan Valley pet owners should know at each stage of life.
What Does Pet Bloodwork Actually Tell Us?
During an exam, we can learn a lot about your pet. We can listen to their heart and lungs, look at their teeth, check their weight, feel their abdomen, and evaluate their overall condition.
Bloodwork lets us look at things we cannot see from the outside.
A complete blood count checks red blood cells, white blood cells, and platelets. A chemistry panel gives us information related to the kidneys, liver, blood sugar, proteins, electrolytes, and other internal processes.
Depending on your pet, we may recommend additional testing such as a urinalysis, thyroid test, or infectious disease screening.
Puppies and Kittens: Bloodwork Is Usually Based on Need
Young pets already have a pretty full veterinary schedule. Between exams, vaccines, parasite prevention, nutrition, and growth, there is a lot to cover.
Healthy puppies and kittens do not necessarily need bloodwork at every visit.
We may recommend it if your young pet has repeated vomiting or diarrhea, poor appetite, unusual tiredness, weakness, poor growth, or another symptom that needs investigating.
Another common time is before a spay, neuter, or other procedure requiring anesthesia.
A puppy can be bouncing around the exam room and still have an internal change we would not know about without testing. Pre-anesthetic bloodwork gives us more information before the procedure begins.
Adult Pets: Healthy Results Still Tell Us Something
When bloodwork comes back normal, that is not wasted information.
It gives us a baseline.
If your dog or cat has bloodwork again a few years later, we can compare the new results with their earlier numbers. That can help us recognize a trend before it turns into a major change.
For some healthy adult pets, bloodwork may be recommended annually. Others may need a different schedule depending on age, breed, lifestyle, medical history, and previous results.
If your pet spends a lot of time outdoors, hikes with you, travels, or has regular contact with other animals, let us know. Lifestyle can help determine which preventive tests make sense too.
Senior Pets: Do Not Blame Everything on Getting Older
Older pets naturally change, but not every change is simply part of aging.
Maybe your dog is drinking more water than usual. Your cat is losing weight but still eating. Your pet is sleeping more, asking to go outside more often, or becoming less interested in normal activities.
Those details matter.
Bloodwork can help us look for conditions involving the kidneys, liver, blood sugar, thyroid, blood cells, and other systems.
Some senior pets may benefit from testing every six to twelve months. Pets with an existing medical condition, medication, or previous abnormal result may need bloodwork more frequently.
There is also no universal age when every dog becomes senior. Larger dogs generally reach that life stage earlier than smaller dogs.
When Should You Call Before the Next Wellness Exam?
If your pet is acting differently, you do not need to wait for their routine appointment.
Persistent vomiting or diarrhea, unexplained weight loss, increased thirst, frequent urination, poor appetite, weakness, pale gums, collapse, unusual fatigue, or significant behavior changes can all be reasons to contact your veterinarian.
Bloodwork may help us narrow down what is happening.
Sometimes we need additional testing after that, such as a urinalysis or imaging. The important thing is getting enough information to decide what your pet needs next.
What If Your Pet Takes Medication?
Some long-term medications come with regular bloodwork recommendations.
We may need to monitor kidney or liver values, blood cells, electrolytes, or whether treatment is having the intended effect.
Your pet may need a blood test after starting medication, after a dose change, and periodically once everything is stable.
Even when your pet feels great, those rechecks can still be important because internal changes are not always obvious at home.
Why Test Before Anesthesia?
A physical exam is an important part of preparing for anesthesia, but it cannot show us everything.
Pre-anesthetic bloodwork gives us additional information about your pet’s health before surgery, dentistry, or another procedure requiring anesthesia.
If something unexpected appears, we may recommend another test, adjust the plan, or postpone an elective procedure. Normal results are useful too and become part of your pet’s medical history.
So, How Often Does Your Pet Need Bloodwork?
There is no magic number.
A healthy young dog may only need bloodwork at certain points. An adult pet may benefit from periodic baseline testing. A senior dog or cat may need more frequent screening. A pet with chronic disease may have an entirely different schedule.
At Johnson Ranch Animal Clinic, we look at your pet as an individual.
If you are not sure when your dog or cat last had bloodwork, ask us at their next visit. We can review their age, health history, medications, lifestyle, and previous results and help you decide what makes sense now.
