Final answer:
Matt is likely going to wash his muddy dog with the hose and soap he gathered, as these actions are indicative of preparing to clean something dirty.
Step-by-step explanation:
From the context given, we can predict that Matt is preparing to wash his dog that is covered in mud. He has retrieved a bottle of soap and turned on a hose, signaling his intent to clean the dog. It's reasonable to infer that he will proceed to wash the mud off his dog using the water from the hose and the soap.
The prediction is based on the standard procedure one would follow when attempting to clean something dirty: in this case, using water and soap to wash away the mud from the dog's coat.
Why This Might Happen
We think this because the actions described (getting soap and turning on a hose) are commonly associated with the act of cleaning. Additionally, the urgency shown by Matt suggests that he wants to clean up the dog before it brings mud into the house.
