Blackberry Bush and trimming

Question

Bought a house this year that had a blackberry bush. Do I need to cut it back for fall/winter? Had a new cane that grew up and the old came I cut down. The new one was tipped at the top at about 4 feet. Now I have long branch offs from this. Just not certain if I need to cut them, as some are over 6 ft in length. Just want some proper guidance. Would love to send a picture. Thank you!
