If you’ve spent a lot of time at home with your dog or puppy, it would be a good idea to start introducing periods of time where your pet is left on their own. This will not only test whether your dog is comfortable with being left, but may also highlight whether this causes anxiety.
A stairgate can be a great way of helping to train your dog to relax when they are on their own. You can start by leaving your dog in a room behind the stairgate randomly throughout the day while you go about your business. Leaving them with a chew or toy, such as a stuffed Kong can help keep them entertained and relaxed, plus make this time apart more enjoyable for your dog.
To begin with, stay where your dog can see you. Over the next few days, increase the amount of time your dog is left behind the gate until they are comfortable with you being completely out of sight. Then, gradually increase the amount of time you leave them alone. For some dogs, this may be a straightforward process, but for others, it can be distressing, and steps should be taken slowly. If your dog becomes too distressed, take the process back a few steps to where they last felt comfortable and try again – building up slowly.
