Schnauzers may be aggressive after neutering because of pain. Dogs will be more sensitive when in pain and become aggressive towards people who are close to them. Secondly, the reason why the Schnauzer is very violent after neutering may be because the dog is more sensitive, and the dog may think that the pain is caused by the owner. Therefore, for some owners who bear grudges, the owner needs to use practical actions to influence the dog again and re-establish trust with the dog.

What should you do if your Schnauzer becomes aggressive after being neutered:

1. After the dog is neutered, you can take it home or make it more familiar and likeable. In such a place, its mood will slowly calm down and it will no longer be so fierce towards people.

2. The dog will be very aggressive after the sterilization operation. The owner can lure it with the snacks it likes to eat, which can have a very good soothing effect.

3. The sterilization operation also has a certain impact on the dog's mind, and the inner fear and fear will last for a period of time. At this time, the owner should take time to provide more companionship and comfort to them.
