Dog Stiff Gait After Heavy Exercise: Causes and Home Care

TL;DR: Post-exercise stiffness in dogs is typically caused by minor muscle fatigue and can be managed with rest, but you should seek veterinary care if the stiffness lasts over 24 hours or if your dog cannot bear weight on a limb.

What causes post-exercise stiffness in my dog?

Just like humans, dogs can experience muscle fatigue or delayed onset muscle soreness (DOMS) after a period of intense activity. This stiff gait is often caused by micro-tears in the muscle fibers or minor inflammation in the joints. It is especially common in dogs that are older, overweight, or those who have sudden bursts of high energy after a sedentary week.

When is my dog's stiff gait considered an emergency?

• The urgency level for a general stiff gait after heavy exercise is Low.
• If your dog is still eating, drinking, and able to move on all four legs, you can typically monitor them at home with rest.
• If the stiffness does not improve within 24 hours, or if your dog is non-weight-bearing on a limb, you should schedule a routine veterinary appointment.

How does a photo or video help a veterinarian triage my dog?

• Capturing a video of your dog’s gait is one of the most helpful tools for a veterinary professional to see exactly how your dog is placing their paws.
• A video allows us to identify which specific joints seem restricted or painful.
• Because dogs often hide their pain or move differently due to adrenaline at the clinic, a video of the behavior happening at home helps us pinpoint if the issue is muscular, joint-related, or neurological.
