Guinea pigs can be walked using a harness and leash. FALSE
Often guinea pigs can escape the harnesses because they aren't made for them. Also any yanking or pulling on the leash can cause the
cavies spine to bend the wrong way causing injury. Guinea pigs aren't dogs and don't need to be walked like dogs.
If you would like for your pig(s) to spend time outdoors, build them a safe, enclosed environment and stay with them the entire time you have them outside.
