Sometimes the relationship between a dog and its owner is so close that the animal begins to be very jealous of “its” person and overly protective of him.
If you notice your dog exhibiting this behavior, do not ignore it: an overprotective dog is unsafe and potentially aggressive.
To do this, you, as the owner of the animal, will need to work on restoring the “hierarchy”: the dog must understand who plays the main role in the house.
To retrain, you can start teaching your dog basic commands like “sit” and “stand,” and if it behaves correctly, reward it with treats.
The next thing that needs to be done is to retrain the dog outside the home, that is, teach it to behave on a leash.
Such pets often pull their owner on the leash, especially when they see other dogs, as their instinct to attack awakens.
Therefore, buy your pet a harness and an adjustable leash - these "accessories" allow the dog to move and not feel oppressed, and at the same time prevent sudden twitching.
When you meet other dogs, stop, give your pet the command “Stand”, wait until the “danger” has passed and resume the walk, giving an encouraging treat.
