Choose a crate that will be large enough for your French bulldog. Your dog should be able to stand normally without a hunched back inside the crate. If your French bulldog isn't fully grown, allow enough room for your puppy to grow into its full adult size. Your dog should also be able to turn around comfortably. Using a crate is one of the best ways to housebreak your French bulldog. The crate also gives your dog a safe space when your dog needs to retreat or you have to leave your dog alone for a little bit. Assemble the crate (if needed) and place a crate pad or soft blanket in the bottom. To encourage your French bulldog to use the crate, put a few healthy treats in the crate, but don't leave food or water in it. Your dog should feel comfortable and safe in its crate. You should place the crate somewhere quiet, but also where your dog can interact with people. Your dog shouldn't feel isolated or punished when your dog's in the crate. Leave the kennel door open and encourage your dog to enter the crate on its own. Let your dog do this often for several days and then shut the door behind your dog. Leave your dog in the crate for 10 minutes and sit next to your during this time. Let your dog out when your dog's quiet. Never let your dog out if your dog is whining or pawing at the door of the crate. Slowly keep your dog in the crate for longer periods of time. Once you've worked up to 30 minutes, you can leave it in the crate for short periods of time. Older dogs can stay in the crate for up to 4 hours at a stretch (which is how long they can hold their bladders). Never leave your dog in a crate for longer than this or use the crate as a punishment. If you do, your dog may resist going in the crate. Make sure your dog's crate is in a quiet spot where people won't be coming and going. To crate your dog overnight, play with your dog a lot so your dog is tired and set a treat in the crate. Close the door once your dog's in the crate and leave the room. Don't reenter the room while your dog is still crying. Remember that you'll still need to get up in the night to let your dog go out and toilet. If your puppy is under 4 months old, let your dog out every 2 to 3 hours. If your dog is older, you should let your dog out at least every 4 hours.
