Dog Lymphoma: Treatment and Welfare

Lymphoma is one of the most common cancers in dogs. Treatment can extend life significantly, but welfare considerations around treatment intensity are important for owners and vets.

Key Facts

Lymphoma accounts for approximately 7-24% of all canine cancers
The CHOP chemotherapy protocol achieves complete remission in around 80-90% of cases
Median survival with treatment is 12-14 months; around 20-25% survive 2+ years
Without treatment, median survival is 4-6 weeks
Certain breeds (Golden Retrievers, Boxers, Bulldogs) have elevated risk
Lymphoma is typically staged I-V based on extent of nodal and organ involvement

Welfare Considerations

Dogs generally tolerate chemotherapy better than humans — most maintain appetite and activity during treatment. However, some experience nausea, fatigue, and infection risk from immune suppression. Welfare-conscious treatment means monitoring quality of life throughout, not just survival time. If a dog's quality of life deteriorates significantly, dose reduction or palliative care is appropriate. Owners should discuss "quality vs. quantity of life" goals explicitly with their oncologist to make decisions aligned with the dog's wellbeing.

What You Can Do

Consult a veterinary oncologist promptly if lymphoma is suspected — early staging improves options
Discuss quality-of-life metrics with your vet alongside treatment efficacy data
Consider palliative (steroid-only) options if full chemotherapy is not appropriate for your dog
Support canine cancer research through organizations like the Morris Animal Foundation
