The couch is probably your refuge after a long hard day and all you want to do is just lie down on the soft thing and relax your muscles. Your dog might feel the same way. If you find it comfortable, why wouldn’t the dog?
Some people let their dog sit on the couch you might not be one of those people. They leave mud and hair on it which can be very undesirable if you come in contact with these things. You probably want to avoid this at all costs.
What Can You Do About It?
First thing you can do is get them an equally soft and comfortable place to sit in. There are dog beds that you can get for your dog and put them in the living room. When they come to sit on the couch, you can show them the right place to sit. But you don’t really have to buy a dog bed. Just go around the house and pick up any extra cushions or blankets or anything that’s soft and put it all together to make a bed out of it all This would surely keep the dog off the couch.
The next thing for you to do would be to train them. Never ever allow them to sit on the couch and instruct everyone in the house to do the same. Every time they sit on it, pick them up and show them the right place to sit. It’s not easy keeping your dogs off the couch of everyone in the house isn’t following this. Just politely nudge them off every time they do it. Training is the way to do it and that too not in a harsh way.
