Walking into a vet appointment without a question list when your dog has DM is one of the easiest ways to leave with answers you didn’t quite get to the questions you actually needed answered.

Quick answer: The most important questions to ask your vet about DM fall into five categories: confirming the diagnosis and ruling out other conditions, tracking progression at follow-up visits, deciding when to introduce a wheelchair, responding when symptoms accelerate, and having honest end-of-life conversations before a crisis forces them. Preparing a written list before each appointment — and bringing a notebook or voice memo to capture answers — makes every visit significantly more useful. DM progresses on its own timeline, so the questions that matter will shift as your dog moves through the stages.

DM appointments tend to be emotionally loaded and logistically rushed. You sit down, your dog is nervous, the vet is kind but busy, and before you know it you’re walking back to your car trying to remember what was actually decided. A question list changes that dynamic entirely. It keeps you in the driver’s seat even when you’re scared.

This guide walks through the questions worth asking at every stage: the first diagnosis appointment, regular follow-ups, the wheelchair conversation, moments of rapid decline, and eventually the hardest conversation of all. I’ve also included a simple printable log at the end you can bring to every appointment.

What Should I Ask at the Initial Diagnosis Appointment?

At the diagnosis appointment, your most important job is to confirm what you’re dealing with and understand what ruling out other conditions actually looked like. DM is diagnosed by exclusion — there’s no single blood test that confirms it — so understanding that process matters.

The University of Missouri College of Veterinary Medicine, which characterized the SOD1 mutation associated with canine DM, emphasizes that a presumptive DM diagnosis requires ruling out other causes of progressive weakness before the label is applied.

Ask these questions clearly:

  • “What conditions did you rule out to reach this diagnosis?” You want to hear that spinal imaging, bloodwork, and a neurological exam have been part of the picture — not just a brief physical.
  • “Is a veterinary neurologist referral appropriate for us?” Your general vet may be excellent, but board-certified neurologists have more tools and experience with atypical presentations. See When to See a Veterinary Neurologist for DM for more on this decision.
  • “My dog’s breed — is the SOD1 mutation relevant, and has genetic testing been done?” The answer shapes the confidence level of the diagnosis.
  • “What stage does my dog appear to be in right now?” Understanding the current stage helps you plan. The DM stages and progression timeline can give you context before and after this conversation.
  • “What can I realistically do to slow the functional decline?” Physical therapy and exercise are widely recommended by rehab specialists as the most evidence-supported interventions. Ask your vet to be specific about what they’d recommend.
  • “What should I watch for that would tell me things are progressing faster than expected?”
Before the Appointment
  • Write down every symptom and when you first noticed it
  • Film a short video of your dog walking — even a phone clip helps the vet enormously
  • Bring a second person if you can; one of you listens while the other writes
  • Ask if the appointment allows enough time for questions, or if a longer consult is available

How Do I Track Progression at Follow-Up Appointments?

Follow-up appointments are most useful when you arrive with documented observations rather than impressions. “She seems a little worse” is harder for a vet to act on than “she started knuckling on the left rear three weeks ago, and by last week both rear legs were affected.”

Between visits, keep a simple log. Note changes in gait, stumbling frequency, falls, stair ability, bladder and bowel control, and your dog’s overall energy and mood. That record becomes the foundation of every follow-up conversation.

Questions to ask at each follow-up:

  • “Based on what you’re seeing today, what stage would you put her in?” Staging helps you track whether the timeline is typical or faster than expected.
  • “Has anything changed in the neurological exam since last time?” Vets assess things you can’t see at home — proprioception (the dog’s awareness of where its feet are), reflexes, and muscle mass.
  • “Is this rate of progression typical for the breed and stage?” Knowing whether your dog is progressing slowly or quickly shapes every decision you’ll make.
  • “Are there any new therapies or supportive interventions worth considering at this stage?” Hydrotherapy, massage, and laser therapy are commonly discussed as DM progresses. Your vet or a rehab specialist can help decide what fits your dog’s current abilities.
  • “When do you want to see us again, and what would make you want to see us sooner?”
Progression Tracking Tips
  • Keep a weekly one-paragraph journal entry — date, what changed, what stayed the same
  • Re-watch old videos of your dog walking and compare them to current ones
  • Track bladder and bowel incidents if incontinence has started — frequency matters
  • Note good days and bad days; DM dogs often have both, and the ratio shifts over time

When Should I Start Asking About a Wheelchair?

The wheelchair conversation should start before your dog stops walking — not after. Most rehab specialists believe dogs learn to use a cart most readily when they still have some hind-leg function and enough energy to push forward. Waiting until your dog is completely non-ambulatory means a steeper learning curve.

Ask your vet these questions when you first notice significant rear-leg weakness:

  • “At what point in my dog’s decline would you recommend introducing a cart?” Get a specific functional marker, not just a vague “when she needs it.”
  • “Should we see a certified canine rehabilitation therapist to help with the fitting and introduction process?” A rehab therapist can fit the cart correctly and teach you how to use it safely.
  • “Which type of cart — two-wheel rear support or four-wheel — makes more sense for my dog’s current condition?” The answer depends on how much front-leg strength remains.
  • “How many hours a day should she use it, and should she still do supported walking outside of cart time?”
  • “What signs would tell me the cart is working well versus causing strain?”

The wheelchair timing guide for DM dogs goes into this in much more detail if you want to prepare before the appointment.

What Do I Ask When Symptoms Accelerate Suddenly?

DM generally progresses slowly and steadily, but some dogs have periods where the decline accelerates noticeably. When that happens, a vet call or visit is appropriate even if the regular appointment isn’t due yet.

When you contact your vet during a faster-declining period, ask:

  • “Is this rate of change consistent with DM, or should we rule out something else happening on top of it?” Concurrent conditions — arthritis, a secondary infection, an unrelated spinal issue — can look like DM worsening.
  • “Has she lost bladder or bowel control, and what does that mean for her care plan right now?” Incontinence management changes significantly at this point, and the DM incontinence care guide can help you prepare the home-care side.
  • “Should we adjust or add any medications for comfort?” DM is not considered a painful condition in its classic form, but secondary muscle soreness and joint stress from compensating movement can be uncomfortable.
  • “What does a reasonable care plan look like for the next four to six weeks, given what’s happening?”
  • “Are we approaching the point where quality of life assessment should be part of our regular conversation?”

How Do I Have the End-of-Life Conversation With My Vet?

This is the question most owners put off the longest, and it’s the one that matters most to get right early. Having the end-of-life conversation before a crisis means you can think clearly, make a plan that actually reflects your dog’s quality of life, and not be making the hardest decision of your life in an emergency.

You can open this conversation simply: “I want to talk about what the signs would look like when comfort care is no longer enough.” A good veterinarian will welcome that question.

Specific things to ask:

  • “What quality-of-life markers do you use to assess a DM dog at late stage?” Ask your vet to name specific signs, not just describe a feeling. The DM quality of life framework can help you build your own framework alongside this conversation.
  • “What would tell you we’re in the last weeks rather than the last months?”
  • “Is in-home euthanasia an option, and how do we arrange it if we decide to go that route?” Many owners find this kinder for both dog and family.
  • “How do we manage pain and comfort in the final stage if she’s not showing classical pain signs?”
  • “What do you recommend we have ready at home so we’re not scrambling at the end?”

The end-of-life planning guide for DM dogs walks through the practical preparation in detail.

Signs That Warrant an Immediate Call
  • Sudden complete loss of hind-leg function in a dog who was still walking
  • New loss of bladder or bowel control when this wasn’t present before
  • Signs of respiratory distress — DM can progress to affect breathing in advanced stages
  • Significant refusal to eat, drink, or engage for more than 24–48 hours
  • Apparent pain or distress that your current medications aren’t managing

Red Flags — Don't Wait for the Next Scheduled Visit
  • Sudden onset of severe symptoms in any previously stable DM dog
  • Loss of deep pain sensation (inability to feel a firm toe pinch)
  • Signs of pressure sores, open wounds, or skin breakdown that aren’t healing
  • Any respiratory changes — labored breathing, unusual sounds, exercise intolerance worse than expected

Frequently Asked Questions

What should I bring to my dog’s first DM diagnosis appointment?

Bring a written list of every symptom you’ve noticed and when it started — even minor things like occasional stumbling or slower stair climbing. Video footage of your dog walking is often more useful to a neurologist than a verbal description. A notebook or phone app to capture what your vet says is just as important.

How often should I schedule follow-up vet appointments for a DM dog?

Most veterinary neurologists recommend check-ins every two to three months during active progression, though this varies with how fast your individual dog is declining. If you notice a meaningful change in function between appointments, don’t wait — call and describe what you’re seeing so your vet can decide whether to move up the visit.

When should I start asking my vet about a wheelchair for my DM dog?

The conversation about wheelchair timing should start before your dog actually needs one. Most rehab specialists suggest introducing a cart while the dog still has some hind-leg function, because that’s when they learn to use it most readily. Ask your vet at the first sign of significant weakness, not after your dog has stopped walking.

How do I start an end-of-life conversation with my vet about my DM dog?

You can open the conversation simply by asking: “What signs would tell you that comfort care is no longer enough?” A good veterinarian will welcome that question rather than avoid it. Having the conversation early — before a crisis — gives you time to think clearly and make a plan that reflects your dog’s quality of life, not just your grief.

Going into a DM appointment prepared doesn’t mean you have all the answers. It means you’re asking the right questions at the right time, which is about the best any of us can do for a dog we love that much.
