Don't worry, I've got the perfect idea. Here's what you can do: first, make sure to keep any food or treats out of reach. Dogs can be quite sneaky, so you'll want to keep your Christmas tree away from any areas where they could potentially get into something they shouldn't. Second, use some positive reinforcement. When your dog approaches the tree, give them a treat or a pat on the head. This will help them learn that the tree is a good thing. Finally, make sure to provide plenty of toys and distractions for your pup.
