Arthritis Flare-Ups in Older Dogs: What to Do on Cold Days

By Dr Duncan Houston

Your older dog was walking reasonably well yesterday but struggles to rise this morning. Cold weather may coincide with a difficult day, but it should not become the automatic explanation.

A change in pain or mobility needs a practical response and, sometimes, reassessment of the diagnosis.

Quick Answer

For a suspected arthritis flare, reduce demanding activity, provide stable footing and continue medicines only as prescribed while contacting your vet for advice. Record what changed and whether your dog can walk, toilet and rest comfortably. Sudden inability to stand, severe pain or a non-weight-bearing limb needs urgent assessment.

Is this definitely arthritis?

Dogs with known arthritis can also injure a ligament, strain a muscle, develop spinal disease or experience another painful illness. A new one-sided limp, obvious swelling or abrupt loss of function should not be dismissed as their usual stiffness.

Even gradual worsening may indicate that the current treatment no longer provides sufficient relief. ACVS osteoarthritis guidance explains why assessment and a combination of treatments are often necessary.

Make the first decisions

What can you safely do now?

1. Move bedding, water and access to toileting onto one level where possible.
2. Lay secure non-slip mats on essential routes and prevent jumping onto furniture.
3. Use short, controlled toilet outings rather than a long walk, running or ball chasing.
4. Keep your dog comfortably warm and dry without direct hot packs or unattended heaters.
5. Follow the existing prescription and call for a treatment review rather than adding leftover drugs.

A suitable support harness can help some dogs, but ask for instruction before lifting a painful or unstable animal. Avoid pulling on limbs or forcing stretches.

What to tell your vet

Describe when the change began, which movements are difficult, any slip or unusual activity, and all medications and supplements. Mention appetite, vomiting, stools, thirst and urination because these can influence treatment decisions. A short video of rising and walking is useful if it can be obtained without making your dog perform painful tasks.

Your vet may examine joints and nerves, review imaging or investigate another cause. A pain plan may need adjustment, but there is no safe universal rescue dose for every older dog.

When is this an emergency?

Seek urgent care for sudden paralysis, severe pain, collapse or a major injury. Black stools, repeated vomiting, marked weakness or refusal of food during anti-inflammatory treatment also require prompt veterinary advice. Do not give the next dose until you have checked what the prescribing vet recommends.

Prevent the next difficult day

Once the flare has been assessed, rebuild manageable activity according to your vet's plan. Regular comfortable movement is generally more useful than alternating prolonged rest with strenuous outings. Maintain lean body condition, keep nails and footing safe, and use an accessible bed.

AAHA pain guidance supports weight optimisation, environmental changes and tailored rehabilitation alongside appropriate medication. Cornell's winter advice adds practical precautions for slippery surfaces and cold exposure.

Common mistakes

• Assuming every new limp is weather-related.
• Combining pain medicines without approval.
• Trying to exercise stiffness out with a long walk.
• Using a supplement as an emergency pain treatment.

Frequently asked questions

Should I massage a painful joint?

Do not press or manipulate an acutely painful area. Ask whether guided rehabilitation is appropriate.

How long should a flare last?

There is no reliable home timetable because the cause may differ. Persistent, worsening or repeated pain needs reassessment.

Is complete rest best?

Temporary activity restriction may be needed, but the longer-term plan should preserve safe movement and muscle.

A difficult day is a signal to reassess comfort. Make essential movement easier and get advice before changing treatment.
