Do dogs respond more to hand signals or verbal commands?

Physical. When you yell a dog commands, make sure your voice is stern and you make eye contact, then say your command and point your finger at what you want it to do, such as to tell it to go to bed. You make eye contact say "bed" in a stern voice then point at the bed and watch it to its bed. Do that for 2-4 days until you say bed without the voice and finger make sure you reward it for doing the command.
