What can we infer about Sam's visit to Josh's house?

The inference that Sam is allergic to dogs might be supported by specific contextual clues in the scenario. If it's mentioned or implied that Sam had a negative reaction to being around Josh's dog, such as sneezing, coughing, or experiencing other symptoms typically associated with allergies, it would lead us to conclude that Sam is allergic.

The context surrounding the visit, such as allowing for Sam's discomfort or the need for Sam to avoid certain areas of the house, can also enhance the understanding that allergies may be a factor in the visit. If other elements like Sam's reactions to the dog's presence during the visit are highlighted, it further reinforces this inference.

To clarify the considerations surrounding other options, being scared to stay at Josh's house after dark ties more to fears associated with the environment rather than a physical ailment, while being scared of dogs directly points to a specific phobia rather than an allergic condition. The notion that Sam doesn't like Josh introduces a relational dynamic that lacks support unless specific evidence of conflict or negative feelings towards him is presented, which doesn't appear to be the case in this scenario.
