Final answer:
For long term pain management of hip dysplasia in an 8-year-old golden retriever with Cushing's Disease, NSAIDs are the best option, while corticosteroids should be avoided due to the dog's condition.
Step-by-step explanation:
The best option for long term pain management of hip dysplasia in an 8-year-old golden retriever with Cushing's Disease would be NSAIDs (non-steroidal anti-inflammatory drugs). While acetaminophen has a lower risk of serious side effects, it may not be strong enough for managing pain associated with osteoarthritis (OA). NSAIDs like ibuprofen can be more effective but come with risks such as gastrointestinal bleeding, elevated blood pressure, and stroke risk. Since the dog has Cushing's Disease, corticosteroids are not a favorable option as they can exacerbate the condition. Opioids are typically reserved for cases where other medications fail and usually recommended for short-term use because of the potential for addiction. Alpha 2 agonists are not commonly used for long-term pain management in OA. Exercise, decreasing stress on joints, and possibly surgery, are additional treatments that may accompany medication for symptom relief.
