The sample sentence I want to say is "The wolf stalked forward slowly, towards him. Nostrils flared, it growled menacingly"
I know the sentence structure is not proper but I'm not able to combine the two sentences without using lots of commas.
It would be great if anyone could help me make it one sentence.
Edit : based on the comments and replies, let me clarify as to what is the word supposed to mean here : it is supposed to mean that the wolf moved ahead without feeling intimidated by the human with the intention of killing him (hence stalking).... Let me know if it is not clear still.
