Vacuum the couch. Use a brush attachment on a vacuum to remove as much of the hair as possible along with daily dirt and debris.
Run a suede brush over the couch. This special brush is available where leather goods are sold. The special brush is designed to remove all debris from the fabric. This will remove the majority of the dog hair from the couch.
Wrap a piece of wide, clear tape around three fingers on one hand with the sticky side out. Run the tape over the couch to collect any dog hair left behind by the previous actions.
