Border Collie The fittest looking dog in the room is usually the one who needs the vet most.
That sounds backwards. Most people picture the wheezy senior Lab snoring in the corner and assume he’s the patient in the room.
But ask a veterinarian who spends real time around working breeds and you’ll hear the same thing over and over: the dogs that hide illness best are the ones bred to keep going no matter what their body is telling them.
Border Collies are the absolute poster children for this. A dog engineered to move stubborn sheep across a wet hillside for six straight hours does not have a well developed instinct for announcing that her hip hurts.
She just keeps going. And going. Right up until something gives.
So annual checkups for this breed aren’t really about confirming what you already suspect. They’re about catching the things your dog is actively, athletically, cheerfully working to hide from you.
Here are the five that belong on your calendar every year, no exceptions.
1. A Real Eye Exam, Not Just a Glance With a Penlight
Border Collies come with a genetic inheritance that includes some legitimately serious eye conditions, and the frustrating part is that most of them progress quietly.
Collie Eye Anomaly is the big one. It’s present from birth, it varies wildly in severity, and mild cases can go completely unnoticed for years.
Progressive Retinal Atrophy is the other name you’ll hear. It does exactly what the name suggests, slowly, and by the time an owner notices their dog hesitating at the top of the stairs, quite a lot of ground has already been lost.
What to actually ask for
A standard wellness visit typically includes a quick look at the eyes. That is not the same thing as an ophthalmic exam.
Request a dilated exam, ideally with a veterinary ophthalmologist if one is within reasonable driving distance. Many areas host low cost screening clinics through breed clubs a few times a year, which is worth knowing if the specialist quote makes you flinch.
A dog who has slowly lost vision will not act blind. She will act like a dog who has memorized her house.
The signs that should move this up your list
Bumping into furniture after you rearrange it. Reluctance in dim light. Suddenly missing the frisbee she used to catch behind her back.
Any of those, and you’re not waiting for the annual. You’re calling this week.
2. Bloodwork With a Full Thyroid Panel Attached
Here’s where a lot of owners get shortchanged without realizing it.
Basic bloodwork is standard at most annual visits, and it’s genuinely useful for spotting kidney values, liver enzymes, and anemia before symptoms show up. But the default panel often includes only a single thyroid value, and a single value is not enough to catch the problem this breed actually gets.
Hypothyroidism shows up in Border Collies more than the average dog. It’s sneaky because the symptoms look like a hundred other things, or like nothing at all.
The symptoms nobody connects to the thyroid
Weight gain despite an unchanged diet. A coat that’s gone dull, thin, or oddly brittle.
Behavior changes are the ones that really slip past people. A dog who used to be relentless and now naps through the afternoon gets written off as "finally mellowing out," when her hormones are the actual explanation.
Ask specifically for a full thyroid panel, not just a screening value. The difference in cost is modest. The difference in what it tells you is not.
Establish a baseline early
The most useful bloodwork is the boring bloodwork you ran three years ago when everything was normal.
Values that sit at the low end of normal mean one thing in isolation and something entirely different when you can see they’ve drifted downward since your dog was four.
3. An Orthopedic and Joint Assessment
This is the one Border Collie owners most often skip, and it’s the one their dogs pay for later.
These dogs jump. They pivot at speed, they slam into stops that would put a human in physical therapy, and they do it all with an enthusiasm that never seems to correlate with how their joints feel afterward.
Hip dysplasia, elbow dysplasia, and cruciate ligament damage all show up in the breed. Osteoarthritis follows behind them like a shadow.
What a good exam includes
Your vet should be flexing and extending every major joint, watching your dog walk and trot, and checking for that subtle resistance that says something is uncomfortable at the far end of its range.
Gait analysis matters here. Ask them to watch your dog move on a hard, non slip surface rather than making a judgment from a dog sitting on an exam table.
If anything looks off, imaging is the next step. Catching early arthritis buys you years of comfortable movement through weight management, supplements, and modified exercise.
The lameness you finally notice is rarely the beginning of the problem. It’s the point where the dog gave up on hiding it.
Watch for the tiny tells
A dog who sits with one leg kicked out to the side. Slower to rise after a nap than she was last year. Choosing the ramp when she used to launch into the truck.
None of that is dramatic. All of it is information.
4. A Dental Evaluation Under the Gum Line
Dental disease is the most common health problem in dogs and also the one owners are most likely to shrug at, which is a rough combination.
By age three, a majority of dogs already have some degree of periodontal disease. That’s not a cosmetic issue. Bacteria from an infected mouth travel, and they don’t have great taste in destinations: heart, liver, kidneys.
Why a visual check isn’t enough
The part of the tooth you can see is the part that’s easy. The problems live below the gum line, where a conscious dog is never going to let anyone look properly.
An annual dental evaluation should include a discussion about whether a full cleaning under anesthesia makes sense that year. Some dogs need it annually. Others go longer.
Border Collies who are heavy chewers deserve extra attention here. Fractured carnassial teeth are common in dogs who go after bones, antlers, and rocks with real conviction, and a slab fracture can hide for months while the tooth quietly abscesses.
The at home habit that changes everything
Brushing. Genuinely, boringly, brushing.
Three or four times a week with an enzymatic toothpaste made for dogs will do more for your vet bills than any dental chew on the shelf.
5. A Cardiac Check and an Honest Body Condition Score
Rounding out the list, two things that get bundled into the physical exam but deserve to be treated as their own event.
The heart first. Your vet should be listening carefully for murmurs and arrhythmias, and in an athletic breed that’s not a formality.
Border Collies can develop patent ductus arteriosus, and various forms of cardiac disease show up as dogs age. A murmur caught early gives you options. A murmur caught during a crisis gives you fewer.
The conversation about weight that you should not dodge
Body condition scoring is the least glamorous item on this entire list and arguably the highest impact.
Studies on lifespan and body condition have been remarkably consistent: dogs kept at a lean weight live meaningfully longer and develop arthritis later than their heavier littermates.
A Border Collie in good condition has a visible waist from above, ribs you can feel easily under a thin layer, and a clear tuck behind the ribcage.
The kindest thing most owners can do for their dog’s joints costs nothing and involves subtracting rather than adding.
Ask your vet for the number, not the vibe. "She looks fine" is not a body condition score, and a lot of dogs sitting at a six out of nine get called fine every single year.
Then write it down, along with everything else from the visit. A year from now, that page is the thing that tells you whether your dog is actually holding steady or just very, very good at pretending she is.
