Dogs can become clingy if they experience a sudden change in their environment, such as moving to a new home, a new baby in the family, or a new pet.
Dogs can learn to be clingy if they are rewarded for this behavior.
Some breeds of dogs are naturally more clingy than others.
Puppies and senior dogs are more likely to be clingy than adult dogs.
Some dogs are simply more independent than others. If your dog is naturally clingy, it may be difficult to change their behavior.
When your dog follows you around, don't give them any attention. This will help them to learn that following you around will not get them what they want.
If your dog's clingy behavior is severe, you may need to seek professional help from a dog trainer or behaviorist.
