Here are a few ways you can prevent your Bulldog from escaping their housing or yard:

1. Make sure your yard is properly fenced: This is especially important if you have a Bulldog, as they are known for their ability to escape. Make sure your fence is tall enough and in good repair to prevent your dog from jumping or digging under it.
2. Use a leash: When you take your Bulldog outside, make sure they are always on a leash. This will prevent them from running off and getting lost.
3. Keep gates and doors secure: Make sure all gates and doors are securely closed and locked. This will prevent your Bulldog from sneaking out when you’re not looking.
4. Use a crate: If you need to leave your Bulldog home alone, consider using a crate to contain them. This will prevent them from getting into mischief or escaping while you’re away.
5. Use a leash and harness: When you take your Bulldog for walks, make sure they are always on a leash and harness. This will prevent them from running off or getting loose.
6. Use a microchip: If your Bulldog does happen to escape, a microchip can help you locate them. Make sure your Bulldog is microchipped and that the information on the chip is up to date.
7. Train your Bulldog: Proper training and socialization can go a long way in preventing your Bulldog from escaping. Make sure to invest in training to ensure that your Bulldog is well-behaved and understands basic commands.
