Border Collie Am I asking the right things in that exam room, or am I just nodding along?
Vet appointments move fast. Fifteen minutes, maybe twenty, and a good chunk of that disappears into the scale, the vaccine paperwork, and your dog quietly attempting to herd the vet tech into a corner.
Then you’re back in the parking lot holding a receipt and a nagging sense that something got skipped.
Border Collies make that feeling worse. The breed carries a specific stack of genetic quirks and behavioral wiring that a busy general practice might only run into a handful of times a year, and almost none of it announces itself during a routine wellness check.
Write these six down. Bring them in. Watch how differently the appointment goes.
1. Has My Dog Been Tested for the MDR1 Mutation?
Start here, because this one can turn an ordinary treatment into an emergency.
The MDR1 mutation (also called ABCB1) affects how a dog’s body handles certain medications. Dogs carrying two copies can’t clear specific drugs out of the brain properly, and the result is neurological toxicity from a dose that would be perfectly safe for the dog next door.
The usual suspects include ivermectin at high doses, loperamide, some sedatives, and a handful of chemotherapy drugs.
Rough Collies get most of the attention here, and Border Collies do carry it at a lower rate. Lower is not zero.
A single cheek swab, done once, protects your dog for the rest of their life. There is no version of this test you have to repeat.
While You’re At It, Ask About the Breed Panel
The same lab that runs MDR1 usually runs the rest of the Border Collie list.
Trapped Neutrophil Syndrome, Ceroid Lipofuscinosis, and Imerslund Grasbeck Syndrome are all rare, all inherited, and all worth knowing about before you breed, before surgery, or before you spend six months chasing vague symptoms.
Ask your vet whether they order these in house or send you to a direct-to-consumer lab. Both work. Knowing which one your clinic prefers saves you a phone call later.
2. When Should We Screen the Eyes, and What Exactly Are We Looking For?
Collie Eye Anomaly is a developmental problem with the tissue behind the retina, and it exists on a spectrum. Some dogs live long, ordinary, frisbee filled lives with a mild form. Others go blind.
Ideally, puppies get examined by a veterinary ophthalmologist between five and eight weeks old, before the developing eye can mask the milder signs. That window closes fast.
Missed it? Genetic testing still tells you whether your dog carries the gene, which matters enormously if breeding is on the table.
The Other Eye Question
Progressive Retinal Atrophy shows up later, often in adulthood, and it moves slowly enough that owners frequently mistake the early stages for clumsiness or stubbornness.
Ask your vet how often they want to see your dog’s eyes as they age. For a breed this reliant on visual precision, a dog who starts hesitating at dusk deserves a real exam and not a shrug.
Herding dogs compensate brilliantly. That’s exactly the problem.
3. What Does Overheating Actually Look Like in a Dog Who Never Quits?
Border Collie Collapse is a real, documented condition, and it’s one of the most misunderstood things about the breed.
Affected dogs work normally for the first five to fifteen minutes of intense activity, then start to wobble. The gait goes sloppy. The back end drags. Some dogs look disoriented or confused, and owners describe them as "drunk."
Then, frustratingly, most of them recover within half an hour and look completely fine, which makes the whole thing easy to dismiss.
The dog who refuses to stop is not telling you they’re fine. They’re telling you they can’t tell you they’re not.
Ask How to Tell It Apart From Heatstroke
This matters in the moment. Heatstroke and BCC can look similar in a hot field, and the immediate response is not identical.
Get your vet’s specific guidance on cooling protocols, when to call ahead, and what your dog’s baseline temperature runs after hard exercise.
Then ask about your own climate. A dog in a mild coastal town and a dog working stock in triple digit summer heat are running very different risk calculations.
4. Is This the Right Weight for a Dog Built to Work?
Border Collies hide weight well under all that coat, and the number on the scale means almost nothing on its own.
What you want is a body condition score. Nine point scale, ideally a four or a five, assessed by hands and not eyeballs.
Ask your vet to walk you through it physically. Show me where I should feel ribs. Show me the tuck. Show me what two pounds too many feels like on this specific dog, because two pounds on a thirty five pound athlete is not nothing.
The Joint Conversation Lives Here Too
Hip dysplasia, elbow issues, and early arthritis all get significantly worse in a dog carrying extra weight.
Ask whether your dog should have hips and elbows evaluated, especially if you’re doing agility, flyball, disc, or serious herding work.
And ask about when. Growth plates in a Border Collie typically close somewhere around twelve to fourteen months, and repetitive high impact work before that closure is a gamble many owners make without ever being told they’re making it.
5. How Do I Tell a Behavior Problem From a Medical One?
Here’s where Border Collie owners get stuck, and where a lot of good dogs get labeled as "just neurotic."
Shadow chasing. Light fixation. Compulsive tail spinning. Fly snapping at nothing.
Everyone assumes boredom. Sometimes it genuinely is boredom, and the fix is a job and a bigger brain workout.
But compulsive behaviors in this breed can also be tied to focal seizure activity, gastrointestinal pain, or vision changes, and none of those get better with more frisbee.
Behavior is data. A vet who treats it that way will find things a trainer never could.
Bring Video
This is the single most useful thing you can do for this question.
Your dog will not perform their weird flashlight ritual in a stainless steel room while a stranger holds a stethoscope on them. They will look like a completely normal dog and you will look like a person who imagines things.
Record three or four clips on your phone. Include the lead up and the aftermath, not just the peak weirdness, because the transitions tell the story.
6. What Does Normal Look Like for This Particular Dog?
Nobody asks this one, and it might be the most valuable question on the list.
Ask your vet to record a real baseline while your dog is healthy: resting heart rate, respiratory rate, gait notes, dental condition, and a full bloodwork panel with the actual numbers and not just a "within normal range" checkbox.
Reference ranges are built around a population of average dogs. Your dog is an obsessive canine athlete with a resting heart rate that might sit comfortably below what a lab flags as low.
Why This Pays Off Later
Seven years from now, a slightly elevated liver value means one of two things.
Either it’s a new problem, or it’s been your dog’s normal since 2026 and nobody wrote it down.
That distinction can be the difference between an expensive diagnostic rabbit hole and a calm "that’s just how she runs."
Ask for a copy of every result, every visit. Keep them in one folder, digital or paper, whichever you’ll actually maintain.
And when you switch vets, move, or end up in an emergency clinic at eleven at night with a dog who collapsed after a fetch session, that folder does the talking while you’re too rattled to remember anything useful.
