There are a few things you can try to prevent your Labrador from digging in the yard or house:

1. Make sure your dog is getting enough exercise and mental stimulation. Bored dogs may start digging to entertain themselves.
2. Provide your dog with a designated digging area in the yard. This could be a small sandbox or a specific area where you have buried toys or treats for your dog to find.
3. Use barriers to block off areas of the yard or house where you don’t want your dog to dig. This could be a physical barrier such as a fence or an invisible fence.
4. Train your dog to stop digging on command. This will require some training and patience, but it can be a very effective way to stop your dog from digging in unwanted areas.
5. If your dog is digging in the house, make sure to keep an eye on your dog when they are inside and redirect their attention to a toy or activity when you see them starting to dig.

It’s important to remember that digging is a natural behavior for dogs, so it may take some time and effort to completely prevent your dog from digging. However, with patience and consistent training, you should be able to successfully stop your dog from digging in unwanted areas.
