Dogs come into our homes as fun, furry, sweet, and cute family pets and they see where we hang out the most, on the couch. They believe, as part of our family, they should just hang out on the couch as well. Many dog owners do not want their dogs on the couch at all unless they invite their dog. So, you may not want to come home from work or walk into your house and see your dog lounging on the couch. However, you may want to chill out for an evening movie with your dog in your lap or laying near you on the couch. Your dog will not always know your rules and why they differ for different times, but you can teach him to stay off of the couch unless you invite him up there.
Training your dog to stay off of the couch unless he is invited is something your dog will understand over time. Be consistent with your training, so he understands he is allowed on the couch if you tell him he is allowed on the couch, but otherwise, the standing rule is that he is not allowed on the couch. This will probably be the toughest thing for your dog to understand because from your dog's perspective, sometimes there's a rule of no couch and sometimes there's a rule of ‘okay you can go on the couch.’ Also, be consistent with your rules, so he understands when you are on the couch and you invite him, he might be allowed as well. However, if you are not on the couch, he is never allowed either. This will take lots of repetition and patience from you both.
