answered 12/14/2007 My Dog Has Hip Pain And I Think Arthritis, What Type Of Medicine Can I Give Her, Aspirin Or Ibuprofen ? She Is Approx. 80-85 Lbs. Lab Mix. You should consider taking the dog to the vet. Large breed dogs are sometimes prone to hip dysplasia. However, if it is arthritis I would think ibuprofin as it is anti-inflamatory.
