What Makes Good Guard Dogs?

When looking at the qualities of a good guard dog you want to look for a few things.

Size: First, you want to make sure that the dog is on the larger side. You don’t want something that is not going to scare an intruder away. You want to make sure the dog can take on a human if the situation arises.

Strength: A guard dog needs to have some strength and confidence so that it can stand its ground against an intruder and scare them off.

If the dog is too cowering in fear the intruder will just push them out of the way and get what they are after.

You also want to consider if the dog is naturally aggressive. Although aggression can be trained out of a dog, it is easier to adopt one that already has a little aggression built in.

An aggressive guard dog will deter most burglars from trying to enter your home, and if they don’t they will be prepared to fight back.

Confident: A good guard dog should be confident and should not back down from a fight. They should know they are strong and they should be confident that they can take on a challenge when needed.

Appearance: A good dog should look fierce and should look intimidating. A person should be intimidated just by looking at their face and size.
