Signs Your Dog Is in Pain: How to Spot It Early and When to Call the Vet

If your dog is in pain, the first clues are often small.

It could be a sudden change in mood, movement, or routine that just feels “not like them”.

Spotting signs of pain in dogs early can protect their quality of life and help your vet treat the cause before it turns into a bigger problem.

Key takeaways

• Subtle signs matter: small changes in behaviour are often the earliest sign of pain.

• Watch movement and comfort: stiffness, limping, and difficulty getting comfortable are classic clues.

• Breathing changes can be important: fast breathing, night panting, and shaking could be a sign.

• Always talk to your vet first about symptoms and safe treatment options.

• When in doubt, record a short video (or use Joii if a Waggel member) and contact your vet. It can really help your vet decide next steps.

Why it can be hard to tell if a dog is in pain

Many dogs keep a brave face. It is instinct. If a dog in the wild shows weakness, it could be dangerous for them. In many cases, this inane behaviour carries over to the home.

So if you are trying to tell if a dog is hurting or sore, you often need to look for the “odd little things” you may notice at home, not big dramatic yelps.

Blue Cross also suggests that dogs can show pain through physical changes and behavioural signs, and you are often best placed to spot early shifts because you know what “normal” looks like for your dog.

Types of pain: acute vs chronic

Generally, there are two different types of pain:

If your dog’s stiffness has crept up over time, it may not be “just getting on a bit”. Chronic pain can quietly chip away at a dog's quality of life, especially in older dogs.

As we've said, a big clue is behaviour. A dog in pain often acts “off” before they look “injured”. You might see:

• Restlessness at night

• Not wanting to be touched

• Hiding, seeming grumpy, or snapping

• Being clingier than usual

These changes are easy to dismiss as “mood”. But they can be a sign of pain or pain and discomfort.

Movement and posture clues

If you are trying to recognise whether your dog may be hurting, look at how they move and rest, so look for:

• Limping or stiffness

• Moving more slowly on walks

• Hesitating at stairs or jumping

• Posture changes (hunched back, head held low, weight shifted)

• Repeatedly standing up and lying down, as if they cannot settle

These are common signs that pain may be getting in the way of their usual, bouncy self.

Panting, fast breathing, shaking, and other “weird” symptoms
Sometimes pain shows up as “odd body stuff”, especially when your dog is resting:

• Panting when they have not exercised

• Fast breathing

• Trembling or shaking

• Panting can be normal. But if your dog is panting heavily at rest, it could be a sign that your dog is experiencing something they are not coping with. If the panting is happening at night, this article adds helpful context: dog panting at night, reasons why.

Eyes, mouth, and tummy clues

Sometimes the signs show up in other ways such as:

• Weepy, squinty eyes

• Drooling or unusual mouth symptoms

• Tummy upset, stool changes

• Foaming at the mouth

If you see any of these symptoms which are not getting any better, please call a vet immediately, but more on that below.

“Call today” signs

It is usually time to talk to your vet if you notice changes that last more than a day, keep coming back, or are getting worse.

Call your vet promptly if:

• Your dog is showing repeated limping or stiffness

• There is a loss of appetite that is new

• They seem withdrawn, snappy, or unusually quiet

• You may notice changes in sleep and settling

• You think your dog is always uncomfortable and it is not improving

If you are stuck in “Should I ring or not?”, a good rule is this: if the signs that a dog is unwell are new for you, trust your instincts and ask your vet.

Emergency now signs (do not wait)

This is “go now” territory. Your dog needs urgent help if:

• Sudden collapse, severe breathing trouble, or very pale gums

• Uncontrolled vomiting, severe bloating, or obvious severe abdominal pain

• Suspected poisoning or severe tremors

• Severe injury, uncontrolled bleeding, or extreme distress

Out-of-hours teams stress not taking a “wait and see” approach with sudden severe pain. (Vets Now).

What happens at the appointment

A veterinarian will usually start with your notes plus a physical exam, then decide if tests are needed. In some cases, the vet may need X-rays or blood tests to pinpoint what is causing pain and decide the safest plan.

If you are curious about what happens in the consult room, this is a useful peek into decision-making, see our interesting behind-the-scenes at the vets' post.

The simple “home notes” that help your vet most

This is one of the best tips to help your dog quickly.
Before you go, jot down:

• When it started

• What makes it better or worse

• Whether they struggle to get up to go outside

• Whether you notice changes in your dog’s eating, sleep, or toilet habits

• A 10-second video of the limp, panting, or odd posture
  A short video is gold. Dogs often act “fine” in the clinic, like they are trying to fool the vet, but earn a treat.

If your dog is experiencing pain, the kindest thing is safe, vet-led pain management.

Depending on the cause, your vet might:

• Advise rest and activity changes

• Prescribe pain relief that is safe for dogs

• Build a longer plan for chronic pain (for example arthritis) to protect your dog’s quality of life

If you are thinking, “Can I give your dog something from my cupboard?”, the safest answer is NO, please don't. Always talk to your veterinarian first. Many human painkillers are dangerous for dogs.

Small home changes that really help

While you wait for the appointment, you can help ease discomfort with simple changes:

• Keep walks short and calm

• Avoid stairs and jumping if that seems to hurt

• Add rugs on slippery floors so they do not skid
  provide a supportive bed

• Use a harness for steadier support, so you are not pulling at the neck

These changes can help keep your dog comfortable without masking symptoms.

You are not being dramatic. You are being a good human and pet parent.

If you notice your dog acting oddly and your gut is nagging you, contact your vet and bring your notes. Early care can help your dog feel better, protect their quality of life, and get you both back to normal routines sooner.
