I suggest a higher one, although if you have a climber, good luck. Lucky has managed to climb over a 30 inch baby gate. Of course, when my parents were dog-sitting, they attempted to barricade her in a laundry room while they were gone with the baby gate across the door, a large, taller card table behind the baby gate, and something above the card table. They got home and Lucky greeted them at the front door, looking rather proud of herself. They checked out the laundry room and nothing was even moved. Lucky is 12 lbs. so they were in disbelief. I think she might be a genius, or at least the most athletic dog ever. She has also managed to escape her crate on a few occasions. We just don't get it. I think she is probably at home now finding a cure for cancer. |
