Dog Cancer Welfare: Pain Assessment and Management

Cancer is the leading cause of death in dogs over 10 years, and welfare-focused pain management is central to quality cancer care.

Key Facts

Cancer causes approximately half of all deaths in dogs over 10 years of age
Pain is a major welfare concern in dogs with bone cancer, oral tumors, and advanced disease
The Glasgow Composite Pain Scale adapts pain assessment for dogs
NSAIDs, opioids, gabapentin, and adjunct therapies provide multimodal pain relief
Palliative care focused solely on comfort is a valid and humane option

Welfare Considerations

Dogs with cancer experience pain that is often underrecognized and undertreated. Unlike humans, dogs cannot verbalize pain and rely on owner and veterinarian vigilance. Multimodal analgesia combining different drug classes provides better pain control than single-drug approaches. Quality of life assessments should guide all treatment decisions.

What You Can Do

Learn the behavioral signs of pain in dogs
Use validated quality of life tools to track your dog's wellbeing during cancer treatment
Ask your vet about multimodal pain management for cancer patients
Consider palliative care as an appropriate primary goal in advanced disease
Work with a veterinary oncologist for specialist pain management guidance
