- Remove the rabbits. If possible, remove the rabbits from the area near the fence so that your dog is no longer tempted to chase them.
- Install a barrier. You can install a physical barrier between your dog and the fence, such as a chicken wire or a piece of plywood. This will make it more difficult for your dog to reach the fence and chew on it.
- Use a deterrent spray. There are a number of commercial sprays available that are designed to deter dogs from chewing on objects. You can apply these sprays to the fence to make it taste unpleasant to your dog.
- Train your dog. You can train your dog to stop chewing on the fence by using positive reinforcement. When your dog is chewing on the fence, immediately say "no" in a firm voice. Then, redirect your dog's attention to something else, such as a toy or a treat.
- Provide your dog with plenty of exercise. A bored dog is more likely to engage in destructive behaviors, such as chewing on the fence. Make sure to give your dog plenty of exercise each day to keep them stimulated and tired.
- Create a safe space. Make sure your dog has a safe and comfortable place to spend time outdoors. This could be a fenced-in yard, a dog park, or even just a designated area in your home. Having a safe space will help to reduce your dog's anxiety and the likelihood of them chewing on the fence.
- Offer mental enrichment activities. Bored dogs are more likely to chew on things they shouldn't. Provide your dog with plenty of mental enrichment activities to keep them entertained, such as interactive toys, puzzle games, and hiding treats around the yard.
- Give your dog some time. It may take time for your dog to learn that they are not allowed to chew on the fence. Be patient and consistent with your training and deterrents, and eventually, your dog should stop chewing on the fence.
