Crate training is an effective way to provide your dog with a safe and comfortable space of their own. Here are some free techniques for crate training your dog:

1. Introduce the crate slowly: Start by introducing your dog to the crate slowly. Place treats and toys inside the crate to encourage your dog to enter on their own. Gradually increase the amount of time your dog spends in the crate until they are comfortable being inside for longer periods.
2. Make the crate comfortable: Make sure the crate is comfortable for your dog by adding a soft blanket or pillow. This will help your dog feel more at ease and relaxed while inside the crate.
3. Use positive reinforcement: Use positive reinforcement to encourage your dog to enter and stay in the crate. Reward your dog with treats and praise when they enter the crate on their own, and gradually decrease the number of treats as your dog becomes more comfortable.
4. Don’t force your dog into the crate: Never force your dog into the crate. This can make them feel scared and anxious, and may even cause them to become aggressive. Instead, encourage your dog to enter the crate on their own.
5. Use the crate as a positive space: Use the crate as a positive space for your dog. Feed them inside the crate and give them treats and toys while they’re inside. This will help your dog associate the crate with positive experiences.
6. Gradually increase time in the crate: Gradually increase the amount of time your dog spends in the crate. Start with short periods of time and gradually increase the duration as your dog becomes more comfortable. This will help prevent your dog from feeling anxious or scared while in the crate.
7. Use the crate for short periods: Use the crate for short periods of time, especially when you’re first starting to crate train your dog. Over time, you can gradually increase the amount of time your dog spends in the crate.
8. Don’t use the crate for punishment: Never use the crate as a form of punishment. This can make your dog fearful of the crate and may even cause them to develop behavior problems.

Overall, crate training is an effective way to provide your dog with a safe and comfortable space of their own. Introduce the crate slowly, make it comfortable, use positive reinforcement, don’t force your dog into the crate, use it as a positive space, gradually increase time in the crate, use the crate for short periods, and don’t use it for punishment, and you’ll soon have a well-trained dog who loves their crate.
