I used a dog playpen and Cali loved it she would go in to it when I got ready to leave and was fine in it. Never climbed out and never chewed. Pixie on the other hand the first week I had her (she was 13 months old when I got her) chewed her way out. The hole was so tiny we didn't see it the first time we came home and she was at the door waiting. So I guess it depends on the puppy |
