How to Understand the Result of The Test

Of course, I understand that people who read this article are not all doctors or dog handlers. So my goal as a doctor to help you understand it. I would doubt this test because not all dogs passed it in equal quantities. Just look for comparison, only 46 Chihuahuas have passed the test, but for some reason as many as 500 Rottweiler. Thus, how can we identify the percentages of aggression refer to this Test?

Conducting the Test

What is this Testbased on? Many aspects are taken into account. What are these aspects? For the stability of the temperament and behavior, aggressiveness, shyness, friendliness. The instinct aspects are also very important and essential. How the dog conducts itself towards the master andthread preservation in the thread. Here is an example, the dog was walking in the streets, where it met different situations. Kids, other dogs or animals like cats and other pets, strangers. The scientists observed how it reacted. There was also strange noise and different things in everyday life which the dog can meet. How the dog reacts and it was the result of the research.

The Speed of Passing the Test

For instance, the percentages that are indicated under each kind shows us how many dogs took part in temperament testing including all dogs of its breed, which were tested. I can explain to you it on the example with Chihuahua. We had 49 dogs but only 32 passed this Test. But the percentage was divided on a common number of dogs (46) in conclusion, the coefficient of passing this test was 69%.

The test determined Failure when:
– Aggression without provocation;
– Panic without possibility to recover;
– Firmly avoidance.

Approach disadvantages
– The ATTC test cannot be considered as an accurate measure and arrangments of aggression. Because firmly avoidance is a failure according to the test.
– As the number of testing dogs was not equal so that the percentage is not clear in this test.

Varied discussion: What are the most dangerous and meanest dog?

According to Cesar Milan, a famous behaviorist thinks that the breed which was artificially made by a human is the most dangerous. But in most cases, dog handlers cannot exactly define, which breed is the most dangerous and the angriest dog in the world.

He is firmly sure that we cannot refer only to statistic and we have to feel deeper in the situation. Anyone who has pit bull (at the time very rough, tough and meanest dog) can prove you how affectionate and even too tender this dog can be if you love it and take care of it with caresses.

I am sure many of you, my readers, have noticed how sometimes similar dogs and masters are. And this is the truth that we can copy each other. I can suppose that people with a certain type of character choose a certain kind of dog and then, in consequence, they train them for special needs, like protection, for example.  If the dog is raised in an aggressive and rude environment it copies the master’s behavior. Even kind and sweet dog can be cruel and dangerous. when you love your pet and reveal him your affectionate attitude, even mean the dog can hardly reveal its instincts.

To Sum Up

This article shows you the view on some aspects which were collected a lot of sources like books, articles, opinion of vets.  I insist that it is not the holy write and you must take into account how kind or aggressive will be your dog depends on many factors and circumstances like environment, your attitude, the background of the dog, how the former master took care of him.

This list is only theory and you have to take it into account as a point of departure. But how things are going between you and your dog and other people will depend only on you and your wise training.

    Hmmmm. This kind of thing makes me anxious. I’m not a huge dog person, but my boyfriend is thinking about getting a German Shepherd and I really just would rather get a cat or like a fish or something haha. I’m probably just a chicken. If I had to get a dog it would probably be a lab, most of those I’ve known have been fairly good with people.

      Mari, It is not the dog! It is the owners and their lack of training or care and confidence. Believe it or not, a dog wants to know that the owner will protect them. My dog looks to me for instruction when another dog approaches , she looks at me for a clue to know she is safe. She is 86lbs! I give clear direction to my dog. I lead on othe walk, she walks along side of me and we don’t need a leash. I can put my hands down her throat to retrieve food. She submits and knows I love her, she knows she is safe. Dogs do not attack humans, unless they are in fear of their lives. And we would do the same, fight back when someone is hurting us. Don’t be with a dog person is you are afraid of dogs. Dogs are lovable and loyal. Also**** look up video of Australian Martin Mckenna who trains dogs. He is fantastic.
