When Your Dog or Cat Becomes a Senior
Senior status starts earlier than most owners expect, and catching things early is most of the benefit.

Most owners are surprised by when their dog or cat officially becomes a senior. It's earlier than the word suggests, and the visits that follow look a little different from the ones your pet has had all along, with more testing and more frequent checkups built in.
When 'senior' actually starts
We consider cats seniors starting at 8 years old, and dogs at 7. That can catch owners off guard, especially with a dog or cat that's still acting completely like themselves. The label isn't about how your pet seems day to day, it's about when the baseline checkup schedule shifts.
The baseline workup
Once your pet reaches senior age, we recommend a baseline exam and diagnostic workup, bloodwork, a fecal test, a urine test, and sometimes X-rays depending on what we find. Bloodwork gives us a look at how the kidneys and liver are functioning, the fecal test checks for parasites, and the urine test tells us things bloodwork alone can't, particularly about kidney function and hydration. This gives us a real reference point for your individual pet, rather than comparing them only to general averages, so if something changes later we know what's actually different for your dog or cat.
Why exams get more frequent
After that baseline, we move to twice-yearly exams, sometimes more depending on what we're watching. Things tend to move faster in senior pets than in younger ones, and a twice-a-year rhythm gives us a much better chance of catching a change while it's still small and manageable, rather than finding out at the next annual visit that something has been building for a while.
Vaccines and preventives don't stop at 'senior'
It's easy to assume that once a pet is older, the routine wellness side of things matters less. It's actually the opposite. Vaccination and prevention protocols stay part of the plan at every visit, senior included, and we adjust them the same individualized way we would for a younger pet, based on your dog or cat's actual health and lifestyle rather than a one-size-fits-all schedule. A senior dog with arthritis, for example, might see less benefit from certain lifestyle-based vaccines than a younger, more active dog would, which is exactly the kind of thing worth reviewing at each visit rather than leaving on autopilot.
Dental health matters just as much for seniors
Dental disease doesn't stop progressing once a pet reaches senior age, and an exam that's already checking bloodwork, kidneys, and joints is also a natural point to check the teeth and gums. A senior pet who's quietly gone off harder kibble or lost some enthusiasm for chew toys is sometimes dealing with dental discomfort rather than simple pickiness, which is one more reason the full workup matters more than any single test on its own.
What we're watching for
The senior workup and follow-up exams are aimed at catching several conditions early, while there's the most room to do something about them:
- Arthritis
- Cancer
- Diabetes
- Heart disease
- Hormone disorders
- Kidney and liver problems
What you might notice first, at home
You see your dog or cat every single day, which puts you in a better position than anyone to notice a small shift, slowing down on the stairs, sleeping more than usual, drinking more water, or being pickier at mealtime. None of those things need to be alarming on their own. They're just worth mentioning at the next exam rather than filing away as 'just getting older.'
None of this is about treating your pet as fragile the moment they hit a certain birthday, it's about shifting how often we look and what we look for, so we can catch things at a stage where there's still the most we can do about them. A senior dog or cat that's still active, eating well, and moving comfortably can absolutely stay that way for years, and the twice-yearly visits are part of how that happens rather than a sign that something's already wrong. If your dog or cat is approaching 7 or 8, or you've noticed something small that's been nagging at you, it's a good time to get on the senior schedule.
