In assessing behavior problems, what medical conditions should be evaluated first?

The correct choice emphasizes the importance of evaluating aggression and house soiling when assessing behavior problems in animals. Both of these behaviors can have underlying medical causes that might manifest as behavioral issues.

Aggression can stem from various health problems, such as pain, discomfort, or neurological disorders, which all need to be ruled out during assessments. Understanding the medical conditions underlying aggressive behaviors is crucial in providing the appropriate interventions or treatments, as these might significantly change the approach to managing the behavior.

House soiling, also known as inappropriate elimination, can be linked to urinary tract infections, bladder problems, or gastrointestinal concerns. These medical issues must be addressed to accurately manage the behavior and to ensure that the animal's physical well-being is not compromised.

By focusing on these two behaviors—aggression and house soiling—the assessment process can be more efficient and effective, leading to better behavioral management strategies as well as improving the animal's overall health.
