My Ten-Year-Old Shih Tzu's Bloodwork Came Back Abnormal — Here's How I Learned to Manage the Whole Picture
The call came on a Wednesday, two days after a routine senior wellness visit for my ten-year-old shih tzu, Bean. I'd brought him in for something I thought was minor, he'd been a little quieter than usual, sleeping more, turning his nose up at food some mornings. The vet did bloodwork as part of the senior panel, and when the office called back, the tech used the phrase "several values are off." She read me a list I didn't understand: elevated liver enzymes, some kidney numbers they wanted to recheck, and a thyroid result that explained why my food-motivated little dog had stopped finishing his breakfast. It was the first time in his life that Bean had come back with anything other than a perfect report.
What I felt wasn't grief, exactly. It was overwhelm. A single dog didn't have one thing wrong with him, he had a handful of things wrong at once, some of them possibly connected, all of them landing on me to manage at a stage of his life when I'd assumed things would get simpler. This is the article I wish someone had handed me that week, because living with a senior dog who has a stack of conditions taught me more about patience and systems than any puppy ever did.
Why This Happens
This is the part that took me months to really absorb: in an older dog, "multiple conditions at once" isn't bad luck, it's the norm. Age does a number on several organ systems independently and simultaneously. The liver gets less efficient, the kidneys filter more slowly, joints stiffen, and the thyroid can slow down and drag the whole metabolism with it. Thyroid function, especially, can explain a cascade of seemingly unrelated signs: weight gain or loss, low energy, poor coat, and a reduced appetite. When one system goes, it can throw off the readings for another, which is why a single abnormal number often isn't the diagnosis, it's a clue that sends the vet looking for the pattern.
The tricky part is that abnormal bloodwork doesn't always mean a serious disease, and normal bloodwork doesn't always mean everything's fine. Liver and kidney values move for lots of reasons: dehydration on the day of the test, a recent meal, a medication, a mild infection, even stress. That's why the first honest answer a vet usually gives is "let's recheck in a few weeks," and why I had to learn not to spiral every time a number was slightly out of range. The job for me wasn't to diagnose Bean. It was to give the vet good input and to manage Bean's daily life carefully between visits.
What I had to accept, too, is that a ten-year-old dog's reality is different from a two-year-old's. We weren't chasing a cure anymore. We were chasing comfort, stability, and good days. That shift in mindset, from "fix it" to "manage it well", was the single most useful change I made.
What I Tried First — and Why It Didn't Work
My first move was the internet, which is how I ended up convinced within an hour that Bean had something hospice-level, and I cried on the kitchen floor. Doom-scrolling a symptom list is not diagnosis, and it nearly made me miss the point. The numbers needed a vet's context, not a search engine's worst case.
Then I tried to "fix" his appetite by buying every premium food and topper on the shelf. I was throwing twelve-dollar cans at a thyroid problem. He'd eat, then not, then eat again. The food was never the issue. His metabolism was, and appetite tricks were a bandage over a misfiring thyroid.
My third mistake was trying to do everything at once. I decided I would overhaul his diet, start four supplements, change his schedule, and add daily walks, all in one week. Bean, who is old and set in his ways, simply refused most of it, and I ended up exhausted and no better off. A senior dog handles change slowly. I'd tried to run a marathon on day one.
What Actually Worked
What I finally understood is that my job was to make Bean's daily life easy and predictable, so that the medical treatment had the best chance of working. Two small things became part of our routine. The first was the Pet Botanics Training Rewards Puppy Bites. I know. They 're puppy treats, but hear me out. They're soft, small, and smell enough to be genuinely motivating, which made them the perfect vehicle for pills. I could bury a capsule in one and Bean would take his medication without a struggle, every time. I used them countless times a day for cooperative care, too, every ear check, every gentle paw handling, every time I needed to look at his gums, a little soft treat reinforced that being handled was safe. For a dog whose days now included a lot of being examined, that was worth its weight in gold.
The second thing was purely for both of us, a low, quiet Glass Terrarium with Airtight Wood Lid that I set up on the windowsill and planted with a little tray of dog-safe wheatgrass. Bean isn't allowed long walks anymore because of his joints, and he gets restless indoors. Having a small living patch of green he could walk over to and gently graze on gave him a pocket of natural, low-impact activity, a tiny piece of the outdoors he could still reach. It sounds like a small thing, and it is. But it turned a bored, cooped-up old dog with nothing to do into a dog with a little daily interest, and that mattered more than I expected for his mood.
The real change, though, was structural. I put every medication on a pill organizer and a calendar, and I set phone alarms, because managing four conditions means you cannot rely on memory, I nearly double-dosed him once and that scared me straight. I wrote down every symptom and behavior in a notebook and brought it to each recheck, so the vet got real data instead of my vague "he seems okay." And I asked for a written treatment plan with what to watch for and what would constitute an emergency, so I wasn't guessing about when to rush in. Between the meds, the treats, the notes, and the little grass patch, Bean's numbers have been stable at each recheck, and the vet called him one of the better-managed seniors she sees. He's still sleeping more. He's still old. But he's comfortable, he's eating, and he still wanders over to that terrarium every afternoon like it's his own little garden.
What I'd Tell Someone Starting Today
First, breathe. An abnormal senior panel is a starting point, not a verdict, and lots of "off" numbers normalize on a recheck. Get the details, ask what each abnormal value could mean, and ask what the plan looks like before you panic. Second, get organized immediately. A pill organizer and phone alarms aren't optional when you're managing more than one condition, and a simple symptom log will make you a vastly more useful partner to your vet.
Third, make comfort the goal. For a ten-year-old dog, the win is good days, not a cure. Keep his environment calm and predictable, give him small reasons to be interested in the day, and find a treat he'll reliably take so medication and handling stop being a battle. And ask directly for an emergency plan, what to watch for, and when to come in. I can't undo Bean's age or his bloodwork. What I can do is make every one of his days as easy as it can be, and that turns out to be an entirely manageable job.
