Question

1. Please take a picture of the dog that is running.

2. Please take a picture of the dog
running.

(Is #2 correct? In Sentence 2 'that is' is missing.)
Ms. Sue
Both are correct.

Writeacher
Both sentences are fine. In #2, "running" seems to be used as a present participle modifying "dog."
