Final answer:
NSAIDs (non-steroidal anti-inflammatory drugs) are the best long-term management option for a golden retriever with both hip dysplasia and Cushing's disease.
Step-by-step explanation:
The best long-term management option for a golden retriever with both hip dysplasia and Cushing's disease would be NSAIDs (non-steroidal anti-inflammatory drugs). NSAIDs, such as ibuprofen, are commonly prescribed to manage joint pain and inflammation associated with hip dysplasia.
However, it is important to note that consulting with a veterinarian is crucial in determining the most appropriate treatment plan for an individual dog. The vet will consider the specific condition of the dog, potential drug-drug interactions with Cushing's disease medication, and any other health concerns before making a final recommendation.
