1. Bury the sides of the kennel. This is probably the most effective way to prevent your dog from digging out. If they can't reach the ground, they can't dig! When you're burying the kennel, make sure to dig deep enough so that your dog can't just climb over the dirt.
2. Cover the kennel with a tarp or chicken wire. This can help deter your dog from digging, but less effective than burying the kennel or using rocks. If you do use a tarp or wire, make sure it is securely attached to the kennel so that your dog can't get underneath it.
3. Fill the hole in with rocks. Placing rocks in a dog run can help prevent a determined digger from escaping. Rocks are especially useful for large dogs who can leap over other barriers, like 2-foot-high chicken wire. However, ensure the rocks are large enough to prevent your dog from carrying them away.
4. Make the kennel taller. If your dog is already able to climb out of the kennel, you may need to make it taller. You can do this by adding an extension to the top or by using a different kennel that is already tall enough.
5. Give your dog plenty of exercise and playtime. A bored dog is a destructive dog. If you give your dog enough exercise and playtime, they will be less likely to dig out of their kennel.
6. Provide your dog with a digging box. Sometimes, dogs just need to dig. If you provide your dog with a digging box, they can dig to their heart's content without damaging your yard or their kennel.
7. Spray the kennel with a bitter apple spray. This can help deter your dog from digging if sprayed around the kennel regularly.
8. Use a vibration or electric fence collar. This type of collar uses a mild electrical stimulation to discourage your dog from digging, but can be cruel and is not recommended.
9. Consult with a professional dog trainer. If you are having trouble stopping your dog from digging out of their kennel, consult with a professional dog trainer. They can help you develop a training plan that is tailored to your dog's individual needs.
